ASUS P2L97-DS User â s Manual 9 II. FEA TURES II. FEA TURES Smart Motherboard Introduction to ASUS Smart Motherboards Performance ⢠SDRAM Optimized Performance: The ASUS Smart Motherboards support the new generation memoryâSynchronous Dynamic Random Access Memory (SDRAM)âwhich increases the data transfer rate from 264MB/s max using EDO memory to 528MB/s max. ⢠Double the IDE T ransfer Speed: The ASUS Smart Motherboards with Intel PIIX4 PCIset improves IDE transfer rate using Bus Master UltraDMA/33 IDE, which can handle data transfers up to 33MB/s. This new technology is compat- ible with existing A T A-2 IDE specifications so there is no need to upgrade cur- rent hard disk drives or cables. ⢠Concurr ent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas- ter busses to memory to CPU. ⢠ACPI Ready: ACPI (Advanced Configuration and Power Interface) is also imple- mented on all ASUS Smart Motherboards. ACPI provides more Ener gy Saving Features for future operating systems (OS) supporting OS Direct Power Man- agement (OSPM) functionality . W ith these features implemented in the OS, PCs can be ready around-the-clock, yet satisfy all the energy saving standards. T o fully utilize the benefits of ACPI, an ACPI-supported OS, such as the successor to W indows 95, must be used. ⢠PC â97 Compliant: Both the BIOS and hardware levels of ASUS Smart Moth- erboards meet PC â97 compliancy . The new PC â97 requirements for systems and components are based on the following high-level goals: support for Plug and Play compatibility and power management for configuring and managing all system components, and 32-bit device drivers and installation procedures for both W indows 95 and W indows NT . Intelligence (with optional LM78 Hardwar e Monitor only): ⢠Fan Status Monitoring and Alarm: T o prevent system overheat and system damage, the CPU fan and system fans are monitored for RPM and failure. Each fan can be set for its normal RPM range and alarm thresholds. ⢠V oltage Monitoring and Alert: System voltage levels are monitored to ensure stable current to critical motherboard components. V oltage specifications are more critical for future processors, so monitoring is necessary to ensure proper system configuration and management.
PB ASUS P2L97-DS User â s Manual II. FEA TURES Smart Motherboard II. FEA TURES ⢠System Resources Alert: T odayâ s operating systems, such as W indows 95, W in- dows NT , and OS/2, require much more memory and hard drive space to present enormous user interfaces and run lar ge applications. The system resource moni- tor will warn the user before the system resources are used up to prevent pos- sible application crashes. Suggestions will give the user information on manag- ing their limited resources more ef ficiently . ⢠Auto Fan Off: The system fans will power of f automatically even in sleep mode . This function reduces both ener gy consumption and system noise, and is a important feature to implement silent PC systems. ⢠Dual Function Power Button (r equir es A TX power supply): The system can be in one of two states, one is Sleep mode and the other is the Soft-Of f mode. Pushing the power button for less than 4 seconds places the system into Sleep mode. When the power button is pressed for more than 4 seconds, it enters the Soft-Off mode. ⢠Remote Ring On (requir es A TX power supply): This allows a computer to be turned on remotely through a modem. W ith this benefit on-hand, any user can access vital information from their computer from anywhere in the world! ⢠Message LED (requir es ACPI OS support): Chassis LEDs now act as infor- mation providers. Through the way a particular LED illuminates, the user can determine the stage the computer is in. A simple glimpse provides useful infor- mation to the user .

PB ASUS P2L97-DS User â s Manual III. INST ALLA TION Jumpers III. INST ALLA TION Installation Steps Before using your computer , you must complete the following steps: 1. Set Jumpers 2. Install DRAM Modules 3. Install the Central Pr ocessing Unit (CPU) 4. Install Expansion Cards 5. Connect Ribbon Cables, Cabinet W ires, and Power Supply 6. Setup the BIOS Softwar e 1. Jumpers Several hardware settings are made through the use of jumper caps to connect jumper pins (JP) on the motherboard. See motherboard layout on page 10 for locations of jumpers. The jumper settings will be described numerically such as [----], [1-2], [2-3] for no connection, connect pins 1&2, and connect pins 2&3 respectively . Pin 1 for our motherboards is always on top PIN 1 or on the left when holding the motherboard with the keyboard connector away from yourself. A â1â is written besides pin 1 on jumpers with three pins. The jumpers will also be shown graphi- cally such as to connect pins 1&2 and to connect pins 2&3. Jumpers with two pins will be shown as for Short (On) and for Open (Of f). For manufacturing simplicity , the jumpers may be sharing pins from other groups. Use the diagrams in this manual instead of following the pin layout on the board. Settings with two jumper numbers require that both jumpers be moved together . T o connect the pins, simply place a plastic jumper cap over the two pins as diagramed. W ARNING! Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. T o protect them against damage from static electric- ity , you should follow some precautions whenever you work on your computer . 1. Unplug your computer when working on the inside. 2. Use a grounded wrist strap before handling computer components. If you do not have one, touch both of your hands to a safely grounded object or to a metal object, such as the power supply case. 3. Hold components by the edges and try not to touch the IC chips, leads o r connectors, o r other components. 4. Place components on a grounded antistatic pad or on the bag that came with the component whenever the components are separated from the system.

26 ASUS P2L97-DS User â s Manual III. INST ALLA TION Expansion Cards III. INST ALLA TION 4. Expansion Cards First read your expansion card documentation for hardware and software settings that may be required to set up your specific card. Expansion Card Installation Procedure 1. Read the documentation for your expansion card. 2. Set any necessary jumpers on your expansion card. 3. Remove your computer systemâ s cover . 4. Remove the bracket on the slot you intend to use. Keep the bracket for possible future use. 5. Carefully align the cardâ s connectors and press firmly . 6. Secure the card on the slot with the screw you removed in step 4. 7. Replace the computer systemâ s cover . 8. Set up the BIOS if necessary (such as IRQ xx Used By ISA: Y es in PNP AND PCI SETUP) 9. Install the necessary software drivers for your expansion card. Assigning IRQs for Expansion Cards Some expansion cards need to use an IRQ to operate. Generally an IRQ must be exclusively assigned to one use. In a standard design there are 16 IRQs available but most of them are already in use, leaving 6 IRQs free for expansion cards. Both ISA and PCI expansion cards may require to use IRQs. System IRQs are avail- able to cards installed in the ISA expansion bus first, then any remaining IRQs are available to PCI cards. Currently , there are two types of ISA cards. The original ISA expansion card design, now referred to as legacy ISA cards, requires that you con- figure the cardâ s jumpers manually and then install it in any available slot on the ISA bus. Y ou may use Microsoft Diagnostics (MSD.EXE) utility located in the W in- dows directory to see a map of your used and free IRQs. If you use W indows 95, the Resources tab under Device Manager displays the resource settings being used by a particular device (to gain access, double-click the System icon under the Contr ol Panel program). Ensure that no two devices share the same IRQs or your computer will experience problems when those two devices are in use at the same time. W ARNING! Unplug your power supply when adding or removing expansion cards or other system components. Failure to do so may cause severe damage to both your motherboard and expansion cards.
ASUS P2L97-DS User â s Manual 27 III. INST ALLA TION T o simplify this process, this motherboard complies with the Plug and Play (PnP) specification, which was developed to allow automatic system configuration when- ever a PnP-compliant card is added to the system. For PnP cards, IRQs are assigned automatically from those available. If the system has both legacy and PnP ISA cards installed, IRQs are assigned to PnP cards from those not used by legacy cards. The PCI and PNP configuration section of the BIOS setup utility can be used to assign which IRQs are being used by legacy cards. For older legacy cards that do not work with the BIOS, you may contact your vendor for an ISA Configuration Utility . An IRQ number is automatically assigned to PCI expansion cards after those used by legacy and PnP ISA cards. In the PCI bus design, the BIOS automatically assigns an IRQ to a PCI slot that contains a card requiring an IRQ. T o install a PCI card, you need to set the INT (interrupt) assignment. Since all the PCI slots on this mother- board use an INT A #, set the jumpers on your PCI cards to INT A. Assigning DMA Channels for ISA Cards Some ISA cards, both legacy and PnP , may also need to use a DMA (Direct Memory Access) channel. DMA assignments for this motherboard are handled the same way as the IRQ assignment process described earlier . Y ou can select a DMA channel in the PCI and PnP configuration section of the BIOS Setup utility . IMPOR T ANT : T o avoid conflicts, reserve the necessary IRQs and DMAs for legacy ISA cards (under PNP AND PCI SETUP of the BIOS SOFTW ARE, choose Ye s in IRQ xx Used By ISA and DMA x Used By ISA for those IRQs and DMAs you want to reserve). ISA Cards and Hardware Monitor The onboard hardware monitor uses the address 290H-297H so legacy ISA cards must not use this address or else conflicts will occur . Accelerated Graphics Port This motherboard provides an accelerated graphics port (AGP) slot to support a new generation of graphics cards with ultra-high memory bandwidth, such as the ASUS AGP-V264GT3 and ASUS AGP-V3000.

The SIZE field auto- matically adjusts according to the configuration you specify . The documentation that comes with your hard disk should provide you with the information regarding the drive specifications. The MODE entry is for IDE hard disks only , and can be ignored for MFM and ESDI drives. This entry provides three options: Normal, Lar ge, LBA , or Auto (see be- low). Set MODE to the Normal for IDE hard disk drives smaller than 528MB; set it to LBA for drives over 528MB that support Logical Block Addressing (LBA) to allow larger IDE hard disks; set it to Lar ge for drives over 528MB that do not sup- port LBA. Lar ge type of drive can only be used with MS-DOS and is very uncom- mon. Most IDE drives over 528MB support the LBA mode.

Some entries are required by the motherboardâ s design to remain in their default settings. A section at the lower right of the screen displays the control keys you can use. T ake note of these keys and their respective uses. If you need information on a particular entry , highlight it and then press <F1>. A pop-up help menu will appear to provide you with the information you need. <F5> loads the last set values, <F6> and <F7> loads the BIOS default values and Setup default values, respectively . NOTE: SETUP Defaults are noted in parenthesis next to each function heading. Details of BIOS Features Setup CPU Internal Cor e Speed This function is reserved for future use and is currently disabled. Boot V irus Detection (Enabled) This field allows you to set boot virus detection, ensuring a virus-free boot sector . This new antivirus solution is unlike native BIOS tools, which of fer limited virus protection typically by write-protecting the partition table. W ith this new solution, your computer is protected against boot virus threats earlier in the boot cycle, that is, before they have a chance to load into your system. This ensures your computer boots to a clean operating system. The system halts and displays a warning message when it detects a virus. If this occurs, you can either allow the operation to continue or use a virus-free bootable floppy disk to restart and investigate your system. Be- cause of conflicts with new operating systems, for example, during installation of new softwares, you may have to set this to Disabled to prevent write errors.

BIOS BIOS Features CPU Level 1 Cache / CPU Level 2 Cache (Enabled) These fields allow you to choose from the default of Enabled or choose Disabled to turn on or off the CPUâ s Level 1 and Level 2 built-in cache. CPU Level 2 Cache ECC Check (Disabled) This function controls the ECC check capability in the CPU level 2 cache. BIOS Update (Enabled) This functions as an update loader integrated into the BIOS to supply the processor with the required data. The BIOS will load the update on all processors during system bootup in the default position of Enabled. Quick Power On Self T est (Enabled) This field speeds up the Power-On Self T est (POST) routine by skipping retesting a second, third, and fourth time. Setup default setting for this field is Enabled . A complete test of the system is done on each test. HDD Sequence SCSI/IDE First (IDE) When using both SCSI and IDE hard disk drives, IDE is always the boot disk using drive letter C (default setting of IDE). This feature allows a SCSI hard disk drive to be the boot disk when set to SCSI. This allows multiple operating systems to be used on both IDE and SCSI drives or the primary operating system to boot using a SCSI hard disk drive. Boot Sequence (A,C) This field determines where the system looks first for an operating system. Options are A,C ; A,CDROM,C ; CDROM,C,A ; D,A ; E,A ; F, A ; C only ; LS/ZIP , C ; and C,A . The setup default setting, A,C, is to check first the floppy disk and then the hard disk drive. Boot Up Floppy Seek (Disabled) When enabled, the BIOS will seek drive A once. Floppy Disk Access Control (R/W) This allows protection of files from the computer system to be copied to floppy disks by allowing the setting of Read Only to only allow reads from the floppy disk drive but not writes. The setup default R/W allows both reads and writes. IDE HDD Block Mode Sectors (HDD MAX) This field enhances hard disk performance by making multi-sector transfers instead of one sector per transfer . Most IDE drives, except older versions, can utilize this feature. Selections are HDD MAX, Disabled, 2, 4, 8, 16, and 32. Security Option (System) When you specify a Supervisor Passwor d and/or User Passwor d (explained later in this section), the Security Option field determines when the system prompts for the password. The default setting is System , where the system prompts for the User Password every time you start your system. The other option is Setup, where the system goes through its startup routine unless the Setup utility is called, when the system prompts for the Supervisor Password.
ASUS P2L97-DS User â s Manual 47 IV . BIOS SOFTW ARE IV . BIOS BIOS Features PS/2 Mouse Function Contr ol (Auto) The default of Auto allows the system to detect a PS/2 mouse on bootup. If detected, IRQ12 will be used for the PS/2 mouse. IRQ12 will be reserved for expansion cards if a PS/2 mouse is not detected. Enabled will always reserve IRQ12, whether on bootup a PS/2 mouse is detected or not. PCI/VGA Palette Snoop (Disabled) Some display cards that are nonstandard VGA such as graphics accelerators or MPEG V ideo Cards may not show colors properly . The setting Enabled should correct this problem. Otherwise leave this on the setup default setting of Disabled. OS/2 Onboard Memory > 64M (Disabled) When using OS/2 operating systems with installed DRAM of greater than 64MB, you need to set this option to Enabled otherwise leave this on Disabled. MPS 1.4 Support (Disabled) MPS 1.4 is Intelâ s Multi-Processor Specification. Some MP operating systems still does not support it. Currently , Novell Netware 4.1 1 SMP (Green River) uses MPS 1.4 for its multi-processor kernel. When Enabled, this adds eight extended entries in the interrupt table. Leave to Disabled if your OS does not support MPS 1.4. ............................................................................................................................... ....... V ideo ROM BIOS Shadow (Enabled) This field allows you to change the video BIOS location from ROM to RAM. Relocat- ing to RAM enhances system performance, as information access is faster than the ROM. C8000-CBFFF to DC000-DFFFF (Disabled) These fields are used for shadowing other expansion card ROMs. If you install other expansion cards with ROMs on them, you will need to know which addresses the ROMs use to shadow them specifically . Shadowing a ROM reduces the memory available between 640K and 1024K by the amount used for this purpose.

ASUS P2L97-DS User â s Manual 60 V . DESKTOP MANAGEMENT Desktop Management Interface (DMI) V . DMI DMI Introduction Introducing the ASUS DMI Configuration Utility This motherboard supports DMI within the BIOS level and provides a DMI Con- figuration Utility to maintain the Management Information Format Database (MIFD). DMI is able to auto-detect and record information pertinent to a computer â s system such as the CPU type, CPU speed, and internal/external frequencies, and memory size. The onboard BIOS will detect as many system information as possible and store those collected information in a 4KB block in the motherboardâ s Flash EPROM and allow the DMI to retrieve data from this database. Unlike other BIOS software, the BIOS on this motherboard uses the same technology implemented for Plug and Play to allow dynamic real-time updating of DMI information versus creating a new BIOS image file and requiring the user to update the whole BIOS. This DMI Con- figuration Utility also allows the system integrator or end user to add additional information into the MIFD such as serial numbers, housing configurations, and ven- dor information. Those information not detected by the motherboard BIOS and has to be manually entered through the DMI Configuration Utility and updated into the MIFD. This DMI Configuration Utility provides the same reliability as PnP updat- ing and will prevent the refreshing failures associated with updating the entire BIOS. System Requirements The DMI Configuration Utility (DMICFG2.EXE) must be used in real mode in order for the program to run, the base memory must be at least 180K. Memory managers like HIMEM.SYS (required by windows) must not be installed. Y ou can boot up from a system diskette without AUTOEXEC.BA T and CONFIG.SYS files, âREMâ HIMEM.SYS in the CONFIG.SYS, or press <F5> during bootup to bypass your AUT OEXEC.BA T and CONFIG.SYS files.

66 ASUS P2L97-DS Userâ s Manual T roubleshooting T ips SCSI Device T roubleshooting Review this checklist if your newly-installed SCSI disk drives, CDROM drives, and other devices do not seem to work properly: ⢠Be sure that termination is correctly set for all devices on the SCSI bus, as described in your host adapter documentation. ⢠Be sure there are no hardware conflicts such as devices in your computer try- ing to use the same interrupts (IRQs) or DMA channels. ⢠Be sure the cables connecting the external and internal SCSI devices and the host adapter are attached securely . Also be sure the pin-1 orientation is correct for internal cables. See the host adapter documentation for more information. ⢠Be sure that each SCSI device connected to the host adapter has a unique SCSI ID. ⢠Be sure CD-ROM drives and other SCSI devices are attached to a power source and are turned ON. Windows95/WindowsNT T roubleshooting What is a miniport driver , and how do I make sure that the miniport driver is installed correctly? Miniport drivers are a new kind of 32bit protect mode device driver used by W in- dows95 and W indowsNT to control host adapters and other kinds of devices. W in- dows95 and W indowsNT include a set of miniport drivers for various types of SCSI host adapters. The host adapter miniport driver is automatically installed and con- figured during W indows95 and W indowsNT installation if your host adapter is al- ready installed. T o make sure the driver is installed correctly in systems running W indows95, open the Control Panel, double-click on System, and click the Device Manager tab. Then double-click the SCSI Controllers icon; you should see the model name of the SCSI host adapter(s) installed in your system. What if there is no SCSI contr ollers icon under Device Manager , or the model name of the SCSI chipset does not appear under Device Manager? If the SCSI controllers icon or your host adapter â s model name do not appear , open Control Panel and double-click the Add New Hardware icon. Let W indows search for the host adapter by selecting Y es on the second screen of the Add New Hardware W izard. If W indows does not detect the host adapter , run the Add New Hardware W izard again. This time, select No on the second screen of the wizard, then select SCSI controllers on the next screen. Select the name of your host adapter when it appears. VII. EZ-SCSI UTILITY T roubleshooting VII. ADAPTEC EZ-SCSI UTILITY
ASUS P2L97-DS User â s Manual 67 VII. ADAPTEC EZ-SCSI UTILITY VII. EZ-SCSI UTILITY T roubleshooting If the name of your SCSI chipset does not appear , you may be able to find its miniport driver on the W indows95 CD-ROM. Follow these steps: 1 Place the W indows95 CD-ROM in your CDROM drive and run the Add New Hardware wizard. 2 Select No on the second screen, and select SCSI controllers on the next screen. 3 Click on the Have Disk button, then click the Browse button. 4 Look in the \drivers\storage directory of the CDROM and select the name of your SCSI host adapter if it appears. What if a yellow exclamation point or a red X appears in Device Manager in front of my host adapter? This means there is some kind of resource problem. First, see if the names of any host adapters appear that are not actually installed in your computer . If so, select the name and click Remove. If a red X appears in front of your host adapter name, remove all the host adapter references under SCSI Controllers and run Add New Hardware, as described in the previous question/answer . If a yellow exclamation point appears in front of your host adapter name, the resources that the driver uses probably do not match the resources used by the hardware. Double-click the host adapter name, then click on the Resource tab. Deselect the Use automatic settings box and edit the resources (Interrupt Request, Direct Memory Access, etc.) so they match those used by the host adapter . If the problem still remains, there is probably a hardware resource conflict between the host adapter and other hardware in your computer . Y ou can fix this by changing the hardware resource settings. (See your hardware documentation.) What do I need to do if I want to use another host adapter? 1 Open the Control Panel, double-click on System, and click the Device Man- ager tab. 2 Double-click the SCSI Controllers icon, select the name of the old host adapter , and click Remove. 3 T urn OFF the computer and physically remove the currently installed host adapter . 4 Install the new host adapter according to the instructions in the hardware docu- mentation. 5 T urn the computer ON. If the new host adapter supports Plug and Play , W in- dows will install and configure it automatically . Otherwise, run Add New Hard- ware to make sure the new driver is loaded.
68 ASUS P2L97-DS Userâ s Manual VII. ADAPTEC EZ-SCSI UTILITY If I am running under W indows95, do I need lines for the Adaptec r eal mode ASPI drivers and mscdex in my config.sys and autoexec.bat files? Usually , you do not need to use these real mode ASPI drivers, because the new W indows miniport drivers support most SCSI host adapters and SCSI devices. How- ever , you need to load the drivers (including mscdex, if you have a CDROM drive) if any of the following is true: ⢠Y ou are running in MSDOS mode ⢠Y ou are using a scanner or another SCSI device with config.sys- or autoexec.bat- based drivers, such as HPâ s sjiix.sys ⢠Y ou have an older model SCSI-1 CDROM drive that W indows95 does not support ⢠Y ou are using a CD-Recorder drive (however , some newer models of CD- Recorder drives can use the embedded W indows miniport drivers) T o install the Adaptec EZSCSI DOS drivers, click the Start button and select Re- start the computer in MS-DOS mode . When the DOS prompt appears, follow the Quick Start instructions for DOS. My CDROM drive doesnât work properly under W indows95. Some older models of SCSI CDROM drives are not compatible with the embedded W indows95 CDROM driver . Y ou can add support for the CDROM drive by doing the following: 1 Click the Start button and select Restart the computer in MS-DOS mode. 2 When the DOS prompt appears, follow the Quick Start instructions for DOS. 3 When you are finished running Adaptec EZSCSI for DOS, find the file named cdtsd.vxd in the windows\system\iosubsys directory and rename it cdtsd.sav . My CDROM drive shows up as more than one icon under My Computer . The mapping between mscdex, which runs in real mode, and the W indows95 CDROM driver does not match. Y ou can correct this in one of two ways: ⢠Comment out the line that loads mscdex.exe in the autoexec.bat file. ⢠Change the /L switch on the line that loads mscdex.exe in the autoexec.bat file so it assigns the CDROM drive the next highest logical drive letter after the hard disk drives.

ASUS P2L97-DS User â s Manual 69 VII. ADAPTEC EZ-SCSI UTILITY VII. EZ-SCSI UTILITY DOS/Win Info. Information for DOS/Windows 3.1x Users The following information may be useful if you install Adaptec EZSCSI on a com- puter running DOS, W indows 3.1x, or W indows for W orkgroups3.1x. NOTE: The Windows95/W indowsNT T roubleshooting section on page 6 de- scribes a few situations when you may need to use the DOS/W indows3.1x driv- ers and ASPI managers under Windows95 or W indowsNT . DOS and Windows3.1x Device Drivers Device drivers are software programs that enable your computer to communicate with SCSI devices such as hard disk drives, CDROM drives, and scanners. Each kind of device requires a dif ferent device driver . Adaptec EZSCSI includes several DOS/W indows3.1x device drivers that are copied to your hard disk during installa- tion. Adaptec EZSCSI adds command lines to your config.sys and autoexec.bat files to load these device drivers if it finds these kinds of devices on your computer . T o learn more about the Adaptec EZSCSI device drivers, including their command line option information, see the online Adaptec EZSCSI Online Reference, a W in- dows Help application. DOS and Windows3.1x ASPI Managers ASPI (Advanced SCSI Programming Interface) managers are software programs that enable the SCSI device drivers, your host adapter , and your SCSI devices to communicate with each other . ASPI managers are written for a specific operating system, such as DOS, and a specific family of Adaptec host adapters. Adaptec EZSCSI includes several ASPI managers for DOS/W indows3.1x. When you install Adaptec EZSCSI on these operating systems, it detects what kind of host adapter is installed in your computer and automatically configures your system with the correct ASPI manager . T o learn more about these ASPI managers, including their command line option information, see the Adaptec EZSCSI Online Reference, a W indows Help application.
70 ASUS P2L97-DS Userâ s Manual DOS Formatting Utilities Adaptec EZSCSI includes several DOS-based formatting utilities: Low-level Formatter (scsifmt) Use the DOS-based scsifmt utility for low-level formatting of SCSI hard disk drives, removable media, Floptical ® drives, and magneto-optical drives. Y ou can also use it to scan a disk device for surface defects before you store data on it. Run scsifmt from the DOS prompt, not from the W indows MSDOS prompt. Before you run it, be sure the disk devices you want to format are connected to the host adapter and that they are powered. Then follow these steps: 1. Change to the directory where scsifmt.exe is located (usually c:\scsi), type scsifmt at the DOS prompt, and press Enter . NOTE: If you ar e formatting a SCSI disk device that supports more than one LUN (for example, Iomegaâ s Bernoulli dual multidrive) type scsifmt / L at the command line. 2. When the first screen appears, read it and press Enter to continue. (Press F1 at any time to view Help.) Information about your SCSI disk devices appears on the screen. 3. Use the arrow keys to move the highlight bar to a disk device you want to format or verify , then press Enter . 4. When the next screen appears, select either Format or V erify (to verify that the disk is free of surface defects), then press Enter . W ARNING! Back up important data before you format the disk device! A low-level format erases all data from the disk. 5. If you select Format, confirm that you want to format the disk, then wait while the disk device is formatted. This may take a long time if the disk is lar ge. If you select V erify , you can press Esc at any time to stop the verification process. (This does not damage the disk.) If the utility finds bad blocks on the disk, it displays information about them. Y ou can reassign the bad block(s) to prevent data from being stored there. 6. Repeat steps 3, 4, and 5, as needed, to format or verify other disk devices. When you are finished, press Esc to exit. VII. ADAPTEC EZ-SCSI UTILITY VII. EZ-SCSI UTILITY Formatting
ASUS P2L97-DS User â s Manual 71 VII. ADAPTEC EZ-SCSI UTILITY VII. EZ-SCSI UTILITY Partitioning Formatter and Partitioner (afdisk) Use the DOS-based afdisk utility to partition and format SCSI hard disk drives, Floptical drives, and magneto-optical drives. Y ou can also use afdisk to remove DOS and non-DOS partitions from a disk drive and to format removable media in standard hard disk format, OS/2 floppy format, or DOS V (Japanese) format. NOTE: Use afdisk only if the disk device is not controlled by the host adapter BIOSâ that is, if the host adapter does not have a BIOS or if its BIOS is not enabled. If the disk device is controlled by the host adapter BIOS, use the DOS fdisk utility to partition and format the disk device. (See the MSDOS documentation.) Run afdisk from the DOS prompt only , not from the W indows MSDOS prompt. Before you run it, be sure the disk devices you want to format and partition are connected to the host adapter and that they are powered. Then follow these steps: 1. Change to the directory where afdisk.exe is located (usually c:\scsi), type afdisk at the DOS prompt, and press Enter . Information about your SCSI disk devices appears on the screen. (The number that appears after T arget is the deviceâ s SCSI ID.) 2. Use the arrow keys to move the highlight bar to the disk device you want to partition, then press Enter . - If the selected disk device is controlled by the host adapter BIOS, you can view information about it but you cannot partition it with afdisk (Use the DOS fdisk and format utilities.) - If the selected disk device is unpartitioned, you must partition it before you can format it. T o do this, follow the instructions on the screen. (Press F1 to see an explanation of the partitioning options.) Information about the selected disk device appears in the lower left of the screen.

ASUS P2L97-DS User â s Manual 9 II. FEA TURES II. FEA TURES Smart Motherboard Introduction to ASUS Smart Motherboards Performance ⢠SDRAM Optimized Performance: The ASUS Smart Motherboards support the new generation memoryâSynchronous Dynamic Random Access Memory (SDRAM)âwhich increases the data transfer rate from 264MB/s max using EDO memory to 528MB/s max. ⢠Double the IDE T ransfer Speed: The ASUS Smart Motherboards with Intel PIIX4 PCIset improves IDE transfer rate using Bus Master UltraDMA/33 IDE, which can handle data transfers up to 33MB/s. This new technology is compat- ible with existing A T A-2 IDE specifications so there is no need to upgrade cur- rent hard disk drives or cables. ⢠Concurr ent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas- ter busses to memory to CPU. ⢠ACPI Ready: ACPI (Advanced Configuration and Power Interface) is also imple- mented on all ASUS Smart Motherboards. ACPI provides more Ener gy Saving Features for future operating systems (OS) supporting OS Direct Power Man- agement (OSPM) functionality . W ith these features implemented in the OS, PCs can be ready around-the-clock, yet satisfy all the energy saving standards. T o fully utilize the benefits of ACPI, an ACPI-supported OS, such as the successor to W indows 95, must be used. ⢠PC â97 Compliant: Both the BIOS and hardware levels of ASUS Smart Moth- erboards meet PC â97 compliancy . The new PC â97 requirements for systems and components are based on the following high-level goals: support for Plug and Play compatibility and power management for configuring and managing all system components, and 32-bit device drivers and installation procedures for both W indows 95 and W indows NT . Intelligence (with optional LM78 Hardwar e Monitor only): ⢠Fan Status Monitoring and Alarm: T o prevent system overheat and system damage, the CPU fan and system fans are monitored for RPM and failure. Each fan can be set for its normal RPM range and alarm thresholds. ⢠V oltage Monitoring and Alert: System voltage levels are monitored to ensure stable current to critical motherboard components. V oltage specifications are more critical for future processors, so monitoring is necessary to ensure proper system configuration and management.
PB ASUS P2L97-DS User â s Manual II. FEA TURES Smart Motherboard II. FEA TURES ⢠System Resources Alert: T odayâ s operating systems, such as W indows 95, W in- dows NT , and OS/2, require much more memory and hard drive space to present enormous user interfaces and run lar ge applications. The system resource moni- tor will warn the user before the system resources are used up to prevent pos- sible application crashes. Suggestions will give the user information on manag- ing their limited resources more ef ficiently . ⢠Auto Fan Off: The system fans will power of f automatically even in sleep mode . This function reduces both ener gy consumption and system noise, and is a important feature to implement silent PC systems. ⢠Dual Function Power Button (r equir es A TX power supply): The system can be in one of two states, one is Sleep mode and the other is the Soft-Of f mode. Pushing the power button for less than 4 seconds places the system into Sleep mode. When the power button is pressed for more than 4 seconds, it enters the Soft-Off mode. ⢠Remote Ring On (requir es A TX power supply): This allows a computer to be turned on remotely through a modem. W ith this benefit on-hand, any user can access vital information from their computer from anywhere in the world! ⢠Message LED (requir es ACPI OS support): Chassis LEDs now act as infor- mation providers. Through the way a particular LED illuminates, the user can determine the stage the computer is in. A simple glimpse provides useful infor- mation to the user .

PB ASUS P2L97-DS User â s Manual III. INST ALLA TION Jumpers III. INST ALLA TION Installation Steps Before using your computer , you must complete the following steps: 1. Set Jumpers 2. Install DRAM Modules 3. Install the Central Pr ocessing Unit (CPU) 4. Install Expansion Cards 5. Connect Ribbon Cables, Cabinet W ires, and Power Supply 6. Setup the BIOS Softwar e 1. Jumpers Several hardware settings are made through the use of jumper caps to connect jumper pins (JP) on the motherboard. See motherboard layout on page 10 for locations of jumpers. The jumper settings will be described numerically such as [----], [1-2], [2-3] for no connection, connect pins 1&2, and connect pins 2&3 respectively . Pin 1 for our motherboards is always on top PIN 1 or on the left when holding the motherboard with the keyboard connector away from yourself. A â1â is written besides pin 1 on jumpers with three pins. The jumpers will also be shown graphi- cally such as to connect pins 1&2 and to connect pins 2&3. Jumpers with two pins will be shown as for Short (On) and for Open (Of f). For manufacturing simplicity , the jumpers may be sharing pins from other groups. Use the diagrams in this manual instead of following the pin layout on the board. Settings with two jumper numbers require that both jumpers be moved together . T o connect the pins, simply place a plastic jumper cap over the two pins as diagramed. W ARNING! Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. T o protect them against damage from static electric- ity , you should follow some precautions whenever you work on your computer . 1. Unplug your computer when working on the inside. 2. Use a grounded wrist strap before handling computer components. If you do not have one, touch both of your hands to a safely grounded object or to a metal object, such as the power supply case. 3. Hold components by the edges and try not to touch the IC chips, leads o r connectors, o r other components. 4. Place components on a grounded antistatic pad or on the bag that came with the component whenever the components are separated from the system.

26 ASUS P2L97-DS User â s Manual III. INST ALLA TION Expansion Cards III. INST ALLA TION 4. Expansion Cards First read your expansion card documentation for hardware and software settings that may be required to set up your specific card. Expansion Card Installation Procedure 1. Read the documentation for your expansion card. 2. Set any necessary jumpers on your expansion card. 3. Remove your computer systemâ s cover . 4. Remove the bracket on the slot you intend to use. Keep the bracket for possible future use. 5. Carefully align the cardâ s connectors and press firmly . 6. Secure the card on the slot with the screw you removed in step 4. 7. Replace the computer systemâ s cover . 8. Set up the BIOS if necessary (such as IRQ xx Used By ISA: Y es in PNP AND PCI SETUP) 9. Install the necessary software drivers for your expansion card. Assigning IRQs for Expansion Cards Some expansion cards need to use an IRQ to operate. Generally an IRQ must be exclusively assigned to one use. In a standard design there are 16 IRQs available but most of them are already in use, leaving 6 IRQs free for expansion cards. Both ISA and PCI expansion cards may require to use IRQs. System IRQs are avail- able to cards installed in the ISA expansion bus first, then any remaining IRQs are available to PCI cards. Currently , there are two types of ISA cards. The original ISA expansion card design, now referred to as legacy ISA cards, requires that you con- figure the cardâ s jumpers manually and then install it in any available slot on the ISA bus. Y ou may use Microsoft Diagnostics (MSD.EXE) utility located in the W in- dows directory to see a map of your used and free IRQs. If you use W indows 95, the Resources tab under Device Manager displays the resource settings being used by a particular device (to gain access, double-click the System icon under the Contr ol Panel program). Ensure that no two devices share the same IRQs or your computer will experience problems when those two devices are in use at the same time. W ARNING! Unplug your power supply when adding or removing expansion cards or other system components. Failure to do so may cause severe damage to both your motherboard and expansion cards.
ASUS P2L97-DS User â s Manual 27 III. INST ALLA TION T o simplify this process, this motherboard complies with the Plug and Play (PnP) specification, which was developed to allow automatic system configuration when- ever a PnP-compliant card is added to the system. For PnP cards, IRQs are assigned automatically from those available. If the system has both legacy and PnP ISA cards installed, IRQs are assigned to PnP cards from those not used by legacy cards. The PCI and PNP configuration section of the BIOS setup utility can be used to assign which IRQs are being used by legacy cards. For older legacy cards that do not work with the BIOS, you may contact your vendor for an ISA Configuration Utility . An IRQ number is automatically assigned to PCI expansion cards after those used by legacy and PnP ISA cards. In the PCI bus design, the BIOS automatically assigns an IRQ to a PCI slot that contains a card requiring an IRQ. T o install a PCI card, you need to set the INT (interrupt) assignment. Since all the PCI slots on this mother- board use an INT A #, set the jumpers on your PCI cards to INT A. Assigning DMA Channels for ISA Cards Some ISA cards, both legacy and PnP , may also need to use a DMA (Direct Memory Access) channel. DMA assignments for this motherboard are handled the same way as the IRQ assignment process described earlier . Y ou can select a DMA channel in the PCI and PnP configuration section of the BIOS Setup utility . IMPOR T ANT : T o avoid conflicts, reserve the necessary IRQs and DMAs for legacy ISA cards (under PNP AND PCI SETUP of the BIOS SOFTW ARE, choose Ye s in IRQ xx Used By ISA and DMA x Used By ISA for those IRQs and DMAs you want to reserve). ISA Cards and Hardware Monitor The onboard hardware monitor uses the address 290H-297H so legacy ISA cards must not use this address or else conflicts will occur . Accelerated Graphics Port This motherboard provides an accelerated graphics port (AGP) slot to support a new generation of graphics cards with ultra-high memory bandwidth, such as the ASUS AGP-V264GT3 and ASUS AGP-V3000.

Either of these memory chips can be updated when BIOS upgrades are re- leased. Use the Flash Memory W riter utility to download the new BIOS file into the ROM chip as described in detail in this section. All computer motherboards provide a Setup utility program for specifying the sys- tem configuration and settings. If your motherboard came in a computer system, the proper configuration entries may have already been made. If so, invoke the Setup utility , as described later , and take note of the configuration settings for future refer- ence; in particular , the hard disk specifications. If you are installing the motherboard, reconfiguring your system or you receive a Run Setup message, you will need to enter new setup information. This section describes how to configure your system using this utility . The BIOS ROM of the system stores the Setup utility . When you turn on the com- puter , the system provides you with the opportunity to run this program. This ap- pears during the Power -On Self T est (POST). Press <Delete> to call up the Setup utility . If you are a little bit late pressing the mentioned key(s), POST will continue with its test routines, thus preventing you from calling up Setup. If you still need to call Setup, reset the system by pressing <Ctrl> <Alt> <Delete>, or by pressing the Reset button on the system case. Y ou can also restart by turning the system off and then back on again. But do so only if the first two methods fail.

Hard Disks This field records the specifications for all non-SCSI hard disk drives installed in your system. The onboard PCI IDE connectors provide Primary and Secondary channels for connecting up to four IDE hard disks or other IDE devices. Each chan- nel can support up to two hard disks; the first of which is the âmasterâ and the second is the âslaveâ. Specifications for SCSI hard disks need not to be entered here since they operate using device drivers and are not supported by any the BIOS. If you install either the optional PCI-SC200 or PCI-SC860 SCSI controller card into the motherboard, see section VI for instructions. If you install other vendorâ s SCSI controller card, refer to their respective documentations on how to install the required SCSI drivers. For IDE hard disk drive setup, you can: ⢠Use the Auto setting for detection during bootup. ⢠Use the IDE HDD AUT O DETECTION in the main menu to automatically enter the drive specifications. ⢠Enter the specifications yourself manually by using the âUserâ option. The entries for specifying the hard disk type include CYLS (number of cylinders), HEAD (number of read/write heads), PRECOMP (write precompensation), LANDZ (landing zone), SECTOR (number of sectors) and MODE . The SIZE field auto- matically adjusts according to the configuration you specify . The documentation that comes with your hard disk should provide you with the information regarding the drive specifications. The MODE entry is for IDE hard disks only , and can be ignored for MFM and ESDI drives. This entry provides three options: Normal, Lar ge, LBA , or Auto (see be- low). Set MODE to the Normal for IDE hard disk drives smaller than 528MB; set it to LBA for drives over 528MB that support Logical Block Addressing (LBA) to allow larger IDE hard disks; set it to Lar ge for drives over 528MB that do not sup- port LBA. Lar ge type of drive can only be used with MS-DOS and is very uncom- mon. Most IDE drives over 528MB support the LBA mode.

Details of BIOS Features Setup CPU Internal Cor e Speed This function is reserved for future use and is currently disabled. Boot V irus Detection (Enabled) This field allows you to set boot virus detection, ensuring a virus-free boot sector . This new antivirus solution is unlike native BIOS tools, which of fer limited virus protection typically by write-protecting the partition table. W ith this new solution, your computer is protected against boot virus threats earlier in the boot cycle, that is, before they have a chance to load into your system. This ensures your computer boots to a clean operating system. The system halts and displays a warning message when it detects a virus. If this occurs, you can either allow the operation to continue or use a virus-free bootable floppy disk to restart and investigate your system. Be- cause of conflicts with new operating systems, for example, during installation of new softwares, you may have to set this to Disabled to prevent write errors.
ASUS P2L97-DS User â s Manual 46 IV . BIOS SOFTW ARE IV . BIOS BIOS Features CPU Level 1 Cache / CPU Level 2 Cache (Enabled) These fields allow you to choose from the default of Enabled or choose Disabled to turn on or off the CPUâ s Level 1 and Level 2 built-in cache. CPU Level 2 Cache ECC Check (Disabled) This function controls the ECC check capability in the CPU level 2 cache. BIOS Update (Enabled) This functions as an update loader integrated into the BIOS to supply the processor with the required data. The BIOS will load the update on all processors during system bootup in the default position of Enabled. Quick Power On Self T est (Enabled) This field speeds up the Power-On Self T est (POST) routine by skipping retesting a second, third, and fourth time. Setup default setting for this field is Enabled . A complete test of the system is done on each test. HDD Sequence SCSI/IDE First (IDE) When using both SCSI and IDE hard disk drives, IDE is always the boot disk using drive letter C (default setting of IDE). This feature allows a SCSI hard disk drive to be the boot disk when set to SCSI. This allows multiple operating systems to be used on both IDE and SCSI drives or the primary operating system to boot using a SCSI hard disk drive. Boot Sequence (A,C) This field determines where the system looks first for an operating system. Options are A,C ; A,CDROM,C ; CDROM,C,A ; D,A ; E,A ; F, A ; C only ; LS/ZIP , C ; and C,A . The setup default setting, A,C, is to check first the floppy disk and then the hard disk drive. Boot Up Floppy Seek (Disabled) When enabled, the BIOS will seek drive A once. Floppy Disk Access Control (R/W) This allows protection of files from the computer system to be copied to floppy disks by allowing the setting of Read Only to only allow reads from the floppy disk drive but not writes. The setup default R/W allows both reads and writes. IDE HDD Block Mode Sectors (HDD MAX) This field enhances hard disk performance by making multi-sector transfers instead of one sector per transfer . Most IDE drives, except older versions, can utilize this feature. Selections are HDD MAX, Disabled, 2, 4, 8, 16, and 32. Security Option (System) When you specify a Supervisor Passwor d and/or User Passwor d (explained later in this section), the Security Option field determines when the system prompts for the password. The default setting is System , where the system prompts for the User Password every time you start your system. The other option is Setup, where the system goes through its startup routine unless the Setup utility is called, when the system prompts for the Supervisor Password.
ASUS P2L97-DS User â s Manual 47 IV . BIOS SOFTW ARE IV . BIOS BIOS Features PS/2 Mouse Function Contr ol (Auto) The default of Auto allows the system to detect a PS/2 mouse on bootup. If detected, IRQ12 will be used for the PS/2 mouse. IRQ12 will be reserved for expansion cards if a PS/2 mouse is not detected. Enabled will always reserve IRQ12, whether on bootup a PS/2 mouse is detected or not. PCI/VGA Palette Snoop (Disabled) Some display cards that are nonstandard VGA such as graphics accelerators or MPEG V ideo Cards may not show colors properly . The setting Enabled should correct this problem. Otherwise leave this on the setup default setting of Disabled. OS/2 Onboard Memory > 64M (Disabled) When using OS/2 operating systems with installed DRAM of greater than 64MB, you need to set this option to Enabled otherwise leave this on Disabled. MPS 1.4 Support (Disabled) MPS 1.4 is Intelâ s Multi-Processor Specification. Some MP operating systems still does not support it. Currently , Novell Netware 4.1 1 SMP (Green River) uses MPS 1.4 for its multi-processor kernel. When Enabled, this adds eight extended entries in the interrupt table. Leave to Disabled if your OS does not support MPS 1.4. ............................................................................................................................... ....... V ideo ROM BIOS Shadow (Enabled) This field allows you to change the video BIOS location from ROM to RAM. Relocat- ing to RAM enhances system performance, as information access is faster than the ROM. C8000-CBFFF to DC000-DFFFF (Disabled) These fields are used for shadowing other expansion card ROMs. If you install other expansion cards with ROMs on them, you will need to know which addresses the ROMs use to shadow them specifically . Shadowing a ROM reduces the memory available between 640K and 1024K by the amount used for this purpose. Boot Up NumLock Status (On) This field enables users to activate the Number Lock function upon system boot. T ypematic Rate Setting (Disabled) When enabled, you can set the two typematic controls listed next.

ASUS P2L97-DS User â s Manual 49 IV . BIOS SOFTW ARE V ideo Memory Cache Mode (UC) USWC (uncacheable, speculative write combining) is a new cache technology for the video memory of the processor . It can greatly improve the display speed by caching the display data. Y ou must leave this on the default setting of UC (uncacheable) if your display card cannot support this feature, otherwise your display may not show properly . PCI 2.1 Support (Enabled) This function allows you to enable or disable PCI 2.1 features. Leave on the default Enabled setting for PCI 2.1 compliancy . Memory Hole At 15Mâ16M (Disabled) Enabling this feature reserves 15MB to 16MB memory address space to ISA expan- sion cards that specifically require this setting. This makes the memory from 15MB and up unavailable to the system. Expansion cards can only access memory up to 16MB. The default is Disabled.

Onboard Serial Port 1 (3F8H/IRQ4) Settings are 3F8H/IRQ4, 2F8H/IRQ3, 3E8H/IRQ4, 2E8H/IRQ10, and Disabled for the onboard serial connector . Onboard Serial Port 2 (2F8H/IRQ3) Settings are 3F8H/IRQ4, 2F8H/IRQ3, 3E8H/IRQ4, 2E8H/IRQ10, and Disabled for the onboard serial connector . Onboard Parallel Port (378H/IRQ7) This field sets the address of the onboard parallel port connector . Y ou can select either: 3BCH / IRQ 7, 378H / IRQ 7, 278H / IRQ 5, Disabled. If you install an I/O card with a parallel port, ensure that there is no conflict in the address assignments. The PC can support up to three parallel ports as long as there are no conflicts for each port. Parallel Port Mode (ECP EPP) This field allows you to set the operation mode of the parallel port. The setting Normal , allows normal-speed operation but in one direction only; EPP allows bidi- rectional parallel port operation at maximum speed; ECP allows the parallel port to operate in bidirectional mode and at a speed faster than the maximum data transfer rate; ECP EPP allows normal speed operation in a two-way mode. ECP DMA Select (3) This selection is available only if you select ECP or ECP EPP in the Parallel Port Mode . Select either DMA Channel 1, 3, or Disable. UAR T2 Use Infrar ed (Disabled) When enabled, this field activates the onboard infrared feature and sets the second serial UAR T to support the infrared module connector on the motherboard. If your system already has a second serial port connected to the onboard COM2 connector , it will no longer work if you enable the infrared feature. By default, this field is set to Disabled , which leaves the second serial port UAR T to support the COM2 serial port connector . See IrDA-compliant infrar ed module connector under section III . Onboard PCI IDE Enable (Both) Y ou can select to enable the primary IDE channel, secondary IDE channel, both, or disable both channels (for systems with only SCSI drives). IDE 0 Master/Slave PIO/DMA Mode, IDE 1 Master/Slave PIO/DMA Mode (Auto) Each channel (0 and 1) has both a master and a slave making four IDE devices possible. Because each IDE device may have a dif ferent Mode timing ( 0, 1, 2, 3, 4), it is necessary for these to be independent. The default setting of Auto will allow auto-detection to ensure optimal performance. IV . BIOS Chipset Features
ASUS P2L97-DS User â s Manual 51 IV . BIOS SOFTW ARE IV . BIOS Power Management Power Management Setup The âPower Management Setupâ option allows you to reduce power consumption. This feature turns of f the video display and shuts down the hard disk after a period of inactivity . NOTE: SETUP Defaults are noted in parenthesis next to each function heading. Details of Power Management Setup Power Management (User Define) This field acts as the master control for the power management modes. Max Saving puts the system into power saving mode after a brief period of system inactivity; Min Saving is almost the same as Max Saving except that this time the system inac- tivity period is longer; Disable disables the power saving features; User Define al- lows you to set power saving options according to your preference. IMPOR T ANT : Advanced Power Management (APM) should be installed to keep the system time updated when the computer enters suspend mode activated by the BIOS Power Management. For DOS environments, you need to add the statement, DEVICE=C:\DOS\POWER.EXE, in you CONFIG.SYS. For W indows 3.x and W in- dows 95, you need to install W indows with the APM feature. A battery and power cord icon labeled âPowerâ will appear in the âControl Panel.â Choose âAdvancedâ in the Power Management Field.

The following options are available: DPMS OFF , DPMS Reduce ON , Blank Scr een , V/H SYNC Blank, DPMS Standby , and DPMS Suspend . The DPMS (Display Power Management System) features allow the BIOS to control the video display card if it supports the DPMS feature. Blank Scr een only blanks the screen (use this for monitors without power management or âgreenâ features. If set up in your system, your screen saver will not display with Blank Scr een selected). V/H SYNC Blank blanks the screen and turns off vertical and horizontal scanning. ....................................................................................................................................... PM T imers This section controls the time-out settings for the Power Management scheme. The fields included in this section are âHDD Power Downâ, which places the hard disk into its lowest power consumption mode, and the Doze, Standby and Suspend sys- tem inactivation modes. The system automatically âwakes upâ from any power saving mode when there is system activity such as when a key is pressed from the keyboard, or when there is activity detected from the enabled IRQ channels. HDD Power Down (Disable) Shuts down any IDE hard disk drives in the system after a period of inactivity . This time period is user -configurable to 1â15 Min or Disable. This feature does not affect SCSI hard drives. Suspend Mode (Disable) Sets the period of time after which each of these modes activate: 1 Min, 2 Min, 4 Min , 8 Min , 10 Min , 20 Min , 30 Min , 1 Hour , 2 Hour , and 4 Hour . ....................................................................................................................................... Power Up Control This section determines the ways the system can be controlled when it is started or restarted, when modem activity is detected, or when power to the computer is inter - rupted and reapplied. The Soft-Off mode refers to powering of f the system through a momentary button switch (A TX switch) or through the software as opposed to disconnecting the AC power by way of a rocker switch or other means. PWR Button < 4 Secs (Soft Off) When set to Soft Off, the A TX switch can be used as a normal system power -off button when pressed for less than 4 seconds. Suspend allows the button to have a dual function where pressing less than 4 seconds will place the system in sleep mode. No Function disables the A TX switch function when the button is pressed under 4 seconds. Regardless of the setting, holding the A TX switch for more than 4 seconds will power of f the system.

ASUS P2L97-DS User â s Manual 54 IV . BIOS SOFTW ARE Plug & Play / PCI IV . BIOS PNP and PCI Setup The âPNP and PCI Setupâ option configures the PCI bus slots. All PCI bus slots on the system use INT A#, thus all installed PCI cards must be set to this value. NOTE: SETUP Defaults are noted in parenthesis next to each function heading. Details of PNP and PCI Setup PNP OS Installed (No) This field allows you to use a Plug-and-Play (PnP) operating system to configure the PCI bus slots instead of using the BIOS. Thus interrupts may be reassigned by the OS when Ye s is selected. When a non-PnP OS is installed or to prevent reassign- ing of interrupt settings, select the default setting of No. Slot 1 (RIGHT) IRQ to Slot 4/5 (LEFT) IRQ (Auto) Thes e fields set how IRQ use is determined for each PCI slot. The default setting for each field is Auto, which uses auto-routing to determine IRQ use. The other options are manual settings of NA, 5, 7, 9, 10, 1 1, 12, 14 or 15 for each slot. PCI Latency T imer (32 PCI Clock) The default setting of 32 PCI Clock enables maximum PCI performance for this motherboard. IRQ xx Used By ISA (No/ICU) These fields indicate whether or not the displayed IRQ for each field is being used by a legacy (non-PnP) ISA card. T wo options are available: No/ICU and Ye s . The first option, the default value, indicates either that the displayed IRQ is not used or an ISA Configuration Utility (ICU) is being used to determine if an ISA card is using that IRQ. If you install a legacy ISA card that requires a unique IRQ, and you are not using an ICU, you must set the field for that IRQ to Ye s . For example: If you install a legacy ISA card that requires IRQ 10, then set IRQ10 Used By ISA to Ye s . ............................................................................................................................... .......
ASUS P2L97-DS User â s Manual 55 IV . BIOS SOFTW ARE IV . BIOS Plug & Play / PCI DMA x Used By ISA (No/ICU) These fields indicate whether or not the displayed DMA channel for each field is being used by a legacy (non-PnP) ISA card. A vailable options include: No/ICU and Ye s . The first option, the default setting, indicates either that the displayed DMA channel is not used or an ICU is being used to determine if an ISA card is using that channel. If you install a legacy ISA card that requires a unique DMA channel, and you are not using an ICU, you must set the field for that channel to Ye s . ISA MEM Block BASE (No/ICU) This field allows you to set the base address and block size of a legacy ISA card that uses any memory segment within the C800H and DFFFH address range. If you have such a card, and you are not using an ICU to specify its address range, select a base address from the six available options; the ISA MEM Block SIZE field will then appear for selecting the block size. If you have more than one legacy ISA card in your system that requires to use this address range, you can increase the block size to either 8K, 16K, 36K, or 64K. If you are using an ICU to accomplish this task, leave ISA MEM Block BASE to its default setting of No/ICU. Onboard AHA BIOS (Auto) The default uses Auto settings for the optional onboard Adaptec 7880 SCSI BIOS. If the onboard Adaptec 7880 SCSI BIOS is not installed or you do not want to use it, choose Disabled. ONB AHA BIOS First (No) This field allows giving priority to the onboard SCSI BIOS for SCSI functions over other controllers. The default is No. USB IRQ (Enabled) Enabled reserves an IRQ# for the USB to work. Disabled does not allow the USB to have an IRQ# and therefore prevents the USB from functioning. If you are not using any USB devices, you may set this feature to Disabled to save an extra IRQ# for expansion cards.

ASUS P2L97-DS User â s Manual 60 V . DESKTOP MANAGEMENT Desktop Management Interface (DMI) V . DMI DMI Introduction Introducing the ASUS DMI Configuration Utility This motherboard supports DMI within the BIOS level and provides a DMI Con- figuration Utility to maintain the Management Information Format Database (MIFD). DMI is able to auto-detect and record information pertinent to a computer â s system such as the CPU type, CPU speed, and internal/external frequencies, and memory size. The onboard BIOS will detect as many system information as possible and store those collected information in a 4KB block in the motherboardâ s Flash EPROM and allow the DMI to retrieve data from this database. Unlike other BIOS software, the BIOS on this motherboard uses the same technology implemented for Plug and Play to allow dynamic real-time updating of DMI information versus creating a new BIOS image file and requiring the user to update the whole BIOS. This DMI Con- figuration Utility also allows the system integrator or end user to add additional information into the MIFD such as serial numbers, housing configurations, and ven- dor information. Those information not detected by the motherboard BIOS and has to be manually entered through the DMI Configuration Utility and updated into the MIFD. This DMI Configuration Utility provides the same reliability as PnP updat- ing and will prevent the refreshing failures associated with updating the entire BIOS. System Requirements The DMI Configuration Utility (DMICFG2.EXE) must be used in real mode in order for the program to run, the base memory must be at least 180K. Memory managers like HIMEM.SYS (required by windows) must not be installed. Y ou can boot up from a system diskette without AUTOEXEC.BA T and CONFIG.SYS files, âREMâ HIMEM.SYS in the CONFIG.SYS, or press <F5> during bootup to bypass your AUT OEXEC.BA T and CONFIG.SYS files.

Also be sure the pin-1 orientation is correct for internal cables. See the host adapter documentation for more information. ⢠Be sure that each SCSI device connected to the host adapter has a unique SCSI ID. ⢠Be sure CD-ROM drives and other SCSI devices are attached to a power source and are turned ON. Windows95/WindowsNT T roubleshooting What is a miniport driver , and how do I make sure that the miniport driver is installed correctly? Miniport drivers are a new kind of 32bit protect mode device driver used by W in- dows95 and W indowsNT to control host adapters and other kinds of devices. W in- dows95 and W indowsNT include a set of miniport drivers for various types of SCSI host adapters. The host adapter miniport driver is automatically installed and con- figured during W indows95 and W indowsNT installation if your host adapter is al- ready installed. T o make sure the driver is installed correctly in systems running W indows95, open the Control Panel, double-click on System, and click the Device Manager tab. Then double-click the SCSI Controllers icon; you should see the model name of the SCSI host adapter(s) installed in your system. What if there is no SCSI contr ollers icon under Device Manager , or the model name of the SCSI chipset does not appear under Device Manager? If the SCSI controllers icon or your host adapter â s model name do not appear , open Control Panel and double-click the Add New Hardware icon. Let W indows search for the host adapter by selecting Y es on the second screen of the Add New Hardware W izard. If W indows does not detect the host adapter , run the Add New Hardware W izard again. This time, select No on the second screen of the wizard, then select SCSI controllers on the next screen. Select the name of your host adapter when it appears. VII.

Follow these steps: 1 Place the W indows95 CD-ROM in your CDROM drive and run the Add New Hardware wizard. 2 Select No on the second screen, and select SCSI controllers on the next screen. 3 Click on the Have Disk button, then click the Browse button. 4 Look in the \drivers\storage directory of the CDROM and select the name of your SCSI host adapter if it appears. What if a yellow exclamation point or a red X appears in Device Manager in front of my host adapter? This means there is some kind of resource problem. First, see if the names of any host adapters appear that are not actually installed in your computer . If so, select the name and click Remove. If a red X appears in front of your host adapter name, remove all the host adapter references under SCSI Controllers and run Add New Hardware, as described in the previous question/answer . If a yellow exclamation point appears in front of your host adapter name, the resources that the driver uses probably do not match the resources used by the hardware. Double-click the host adapter name, then click on the Resource tab. Deselect the Use automatic settings box and edit the resources (Interrupt Request, Direct Memory Access, etc.) so they match those used by the host adapter . If the problem still remains, there is probably a hardware resource conflict between the host adapter and other hardware in your computer . Y ou can fix this by changing the hardware resource settings. (See your hardware documentation.) What do I need to do if I want to use another host adapter? 1 Open the Control Panel, double-click on System, and click the Device Man- ager tab. 2 Double-click the SCSI Controllers icon, select the name of the old host adapter , and click Remove. 3 T urn OFF the computer and physically remove the currently installed host adapter . 4 Install the new host adapter according to the instructions in the hardware docu- mentation. 5 T urn the computer ON. If the new host adapter supports Plug and Play , W in- dows will install and configure it automatically . Otherwise, run Add New Hard- ware to make sure the new driver is loaded.
68 ASUS P2L97-DS Userâ s Manual VII. ADAPTEC EZ-SCSI UTILITY If I am running under W indows95, do I need lines for the Adaptec r eal mode ASPI drivers and mscdex in my config.sys and autoexec.bat files? Usually , you do not need to use these real mode ASPI drivers, because the new W indows miniport drivers support most SCSI host adapters and SCSI devices. How- ever , you need to load the drivers (including mscdex, if you have a CDROM drive) if any of the following is true: ⢠Y ou are running in MSDOS mode ⢠Y ou are using a scanner or another SCSI device with config.sys- or autoexec.bat- based drivers, such as HPâ s sjiix.sys ⢠Y ou have an older model SCSI-1 CDROM drive that W indows95 does not support ⢠Y ou are using a CD-Recorder drive (however , some newer models of CD- Recorder drives can use the embedded W indows miniport drivers) T o install the Adaptec EZSCSI DOS drivers, click the Start button and select Re- start the computer in MS-DOS mode . When the DOS prompt appears, follow the Quick Start instructions for DOS. My CDROM drive doesnât work properly under W indows95. Some older models of SCSI CDROM drives are not compatible with the embedded W indows95 CDROM driver . Y ou can add support for the CDROM drive by doing the following: 1 Click the Start button and select Restart the computer in MS-DOS mode. 2 When the DOS prompt appears, follow the Quick Start instructions for DOS. 3 When you are finished running Adaptec EZSCSI for DOS, find the file named cdtsd.vxd in the windows\system\iosubsys directory and rename it cdtsd.sav . My CDROM drive shows up as more than one icon under My Computer . The mapping between mscdex, which runs in real mode, and the W indows95 CDROM driver does not match. Y ou can correct this in one of two ways: ⢠Comment out the line that loads mscdex.exe in the autoexec.bat file. ⢠Change the /L switch on the line that loads mscdex.exe in the autoexec.bat file so it assigns the CDROM drive the next highest logical drive letter after the hard disk drives.

ASUS P2L97-DS User â s Manual 69 VII. ADAPTEC EZ-SCSI UTILITY VII. EZ-SCSI UTILITY DOS/Win Info. Information for DOS/Windows 3.1x Users The following information may be useful if you install Adaptec EZSCSI on a com- puter running DOS, W indows 3.1x, or W indows for W orkgroups3.1x. NOTE: The Windows95/W indowsNT T roubleshooting section on page 6 de- scribes a few situations when you may need to use the DOS/W indows3.1x driv- ers and ASPI managers under Windows95 or W indowsNT . DOS and Windows3.1x Device Drivers Device drivers are software programs that enable your computer to communicate with SCSI devices such as hard disk drives, CDROM drives, and scanners. Each kind of device requires a dif ferent device driver . Adaptec EZSCSI includes several DOS/W indows3.1x device drivers that are copied to your hard disk during installa- tion. Adaptec EZSCSI adds command lines to your config.sys and autoexec.bat files to load these device drivers if it finds these kinds of devices on your computer . T o learn more about the Adaptec EZSCSI device drivers, including their command line option information, see the online Adaptec EZSCSI Online Reference, a W in- dows Help application. DOS and Windows3.1x ASPI Managers ASPI (Advanced SCSI Programming Interface) managers are software programs that enable the SCSI device drivers, your host adapter , and your SCSI devices to communicate with each other . ASPI managers are written for a specific operating system, such as DOS, and a specific family of Adaptec host adapters. Adaptec EZSCSI includes several ASPI managers for DOS/W indows3.1x. When you install Adaptec EZSCSI on these operating systems, it detects what kind of host adapter is installed in your computer and automatically configures your system with the correct ASPI manager . T o learn more about these ASPI managers, including their command line option information, see the Adaptec EZSCSI Online Reference, a W indows Help application.
70 ASUS P2L97-DS Userâ s Manual DOS Formatting Utilities Adaptec EZSCSI includes several DOS-based formatting utilities: Low-level Formatter (scsifmt) Use the DOS-based scsifmt utility for low-level formatting of SCSI hard disk drives, removable media, Floptical ® drives, and magneto-optical drives. Y ou can also use it to scan a disk device for surface defects before you store data on it. Run scsifmt from the DOS prompt, not from the W indows MSDOS prompt. Before you run it, be sure the disk devices you want to format are connected to the host adapter and that they are powered. Then follow these steps: 1. Change to the directory where scsifmt.exe is located (usually c:\scsi), type scsifmt at the DOS prompt, and press Enter . NOTE: If you ar e formatting a SCSI disk device that supports more than one LUN (for example, Iomegaâ s Bernoulli dual multidrive) type scsifmt / L at the command line. 2. When the first screen appears, read it and press Enter to continue. (Press F1 at any time to view Help.) Information about your SCSI disk devices appears on the screen. 3. Use the arrow keys to move the highlight bar to a disk device you want to format or verify , then press Enter . 4. When the next screen appears, select either Format or V erify (to verify that the disk is free of surface defects), then press Enter . W ARNING! Back up important data before you format the disk device! A low-level format erases all data from the disk. 5. If you select Format, confirm that you want to format the disk, then wait while the disk device is formatted. This may take a long time if the disk is lar ge. If you select V erify , you can press Esc at any time to stop the verification process. (This does not damage the disk.) If the utility finds bad blocks on the disk, it displays information about them. Y ou can reassign the bad block(s) to prevent data from being stored there. 6. Repeat steps 3, 4, and 5, as needed, to format or verify other disk devices. When you are finished, press Esc to exit. VII. ADAPTEC EZ-SCSI UTILITY VII. EZ-SCSI UTILITY Formatting
ASUS P2L97-DS User â s Manual 71 VII. ADAPTEC EZ-SCSI UTILITY VII. EZ-SCSI UTILITY Partitioning Formatter and Partitioner (afdisk) Use the DOS-based afdisk utility to partition and format SCSI hard disk drives, Floptical drives, and magneto-optical drives. Y ou can also use afdisk to remove DOS and non-DOS partitions from a disk drive and to format removable media in standard hard disk format, OS/2 floppy format, or DOS V (Japanese) format. NOTE: Use afdisk only if the disk device is not controlled by the host adapter BIOSâ that is, if the host adapter does not have a BIOS or if its BIOS is not enabled. If the disk device is controlled by the host adapter BIOS, use the DOS fdisk utility to partition and format the disk device. (See the MSDOS documentation.) Run afdisk from the DOS prompt only , not from the W indows MSDOS prompt. Before you run it, be sure the disk devices you want to format and partition are connected to the host adapter and that they are powered. Then follow these steps: 1. Change to the directory where afdisk.exe is located (usually c:\scsi), type afdisk at the DOS prompt, and press Enter . Information about your SCSI disk devices appears on the screen. (The number that appears after T arget is the deviceâ s SCSI ID.) 2. Use the arrow keys to move the highlight bar to the disk device you want to partition, then press Enter . - If the selected disk device is controlled by the host adapter BIOS, you can view information about it but you cannot partition it with afdisk (Use the DOS fdisk and format utilities.) - If the selected disk device is unpartitioned, you must partition it before you can format it. T o do this, follow the instructions on the screen. (Press F1 to see an explanation of the partitioning options.) Information about the selected disk device appears in the lower left of the screen. Disks smaller than 1Gigabyte have 64 heads, 32 sectors per track, and cylinders equal to the number of MBytes of available capacity . Disks lar ger than 1Gigabyte have 255 heads, 63sectors per track, and one cylinder per 8MBytes of available capacity .
