12 ASUS P/I-P55T2P4S User ’ s Manual III. INST ALLA TION Installation Steps Before using your computer , you must complete the following steps: 1. Set Jumpers on the Motherboard 2. Install DRAM Modules 3. Install the Central Pr ocessing Unit (CPU) 4. Install Expansion Cards 5. Connect Ribbon Cables, Cabinet W ir es, 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 "Map of the Motherboard" on page 4 for loca- tions 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 respec- tively . Pin 1 for our motherboards is always on top Pin 1 or on the left Pin 1 when holding the motherboard with the keyboard connector away from yourself. A "1" is written besides pin 1 on jumpers with three pins. The jumpers will also be shown graphically 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 (Off). 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 to- gether . T o connect the pins, simply place a plastic jumper cap over the two pins as diagramed. W ARNING: Computer motheboards and components contain very delicate Integrated Circuit (IC) chips. T o protect the motherboard and other compo- nents against damage from static electricity , you should follow some precau- tions whenever you work on your computer . 1. Unplug your computer when working on the inside. 2. Hold components by the edges and try not to touch the IC chips, leads, or circuitry . 3. Use a grounded wrist strap before handling computer 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. (Jumpers) III. INST ALLA TION

ASUS P/I-P55T2P4S User’ s Manual 21 III. INST ALLA TION 3. Central Processing Unit (CPU) The motherboard provides a 321-pin ZIF Socket 7 that is backwards compatible with ZIF Socket 5 processors. The CPU that came with the motherboard should have a fan attached to it to prevent overheating. If this is not the case then purchase a fan before you turn on your system. Apply thermal jelly to the CPU top and then install the fan onto the CPU. W ARNING: W ithout a fan circulating air on the CPU and heat sinks, the CPU and/or heat sinks can overheat and cause damage to both the CPU and the motherboard. (See "CPU Cooling Fan Connector” at the end of this section.) T o install a CPU, first turn of f your system and remove its cover . Locate the ZIF socket and open it by first pulling the lever sideways away from the socket then upwards to a 90-degree right angle. Insert the CPU with the correct orientation as shown. Use the notched corner of the CPU with the white dot as your guide. The white dot should point towards the end the of the lever . Notice that there is a blank area where one hole is missing from that corner of the square array of pin holes and a "1" printed on the motherboard next to that corner . Because the CPU has a corner pin for three of the four corners, the CPU will only fit in the one orientation as shown. The picture is for reference only; you should have a CPU fan that will cover the face of the CPU. W ith the added weight of the CPU fan, no force is required to insert the CPU. Once completely inserted, hold down on the fan and close the socket's lever . IMPOR T ANT : Y ou must set jumpers for "CPU to BUS Fr equency Ratio" and jumpers for "BUS Fr equency Selection" depending on the CPU that you install.

22 ASUS P/I-P55T2P4S User ’ s Manual III. INST ALLA TION 4. Expansion Cards IMPOR T ANT : PCI Slot 1 share the same interrupt number (INT A#) with the onboard 7880 SCSI chipset, therefor e PCI Slot 1 cannot use expansion cards which requir e an interrupt number . Use the other PCI Slots first. If you need all the slots, try using your display card on PCI Slot 1 because some display cards do not use an interrupt number . First read your expansion card documentation on any hardware and software settings that may be required to setup your specific card. NOTE: PCI Slot 4 has a MediaBus extension 2.0 which allows the installation of a PCI card or a MediaBus card (optional multifunctional card) but not both. 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 system's cover . 4. Remove the bracket on the slot you intend to use. Keep the bracket for pos- sible future use. 5. Carefully align the card’ s connectors and press firmly . 6. Secure the card on the slot with the screw you removed in step 4. 7. Replace the computer system's cover . 8. Setup 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 an standard design there are 16 IRQs available but most of them are already in use by parts of the system which leaves 6 free for expansion cards. W ARNING: Make sure that you 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. (Expansion Cards) III. INST ALLA TION
ASUS P/I-P55T2P4S User’ s Manual 23 III. INST ALLA TION Both ISA and PCI expansion cards may need to use IRQs. System IRQs are avail- able to cards installed in the ISA expansion bus first, and any remaining IRQs are then used by 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 configure the card’ s jumpers manually and then install it in any available slot on the ISA bus. Y ou may use Microsoft's Diagnostic (MSD.EXE) utility included in the W indows directory to see a map of your used and free IRQs. For W indows 95 users, the "Control Panel" icon in "My Computer ," contains a "System" icon which gives you a "Device Manager" tab. Double clicking on a specific device give you "Resources" tab which shows the Interrupt number and address. Make sure that no two devices use the same IRQs or your computer will experience problems when those two devices are in use at the same time. T o simplify this process this motherboard has complied 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 as- signed 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 of the BIOS setup utility can be used to indicate which IRQs are being used by Legacy cards. For older Legacy cards that does not work with the BIOS, you can 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 has a card in it that requires an IRQ. T o install a PCI card, you need to set something called the INT (interrupt) assignment. Since all the PCI slots on this motherboard use an INT A #, be sure that the jumpers on your PCI cards are set 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 above. Y ou can select a DMA channel in the PCI and PNP configuration section of the BIOS Setup utility . IMPOR T ANT : Choose "Y es" for those IRQ's and DMA's you wish to r eserve for Legacy (Non-PnP) ISA expansion cards in “IRQ xx Used By ISA” and “DMA x Used By ISA” of the PNP and PCI Setup in the BIOS SOFTW ARE section, otherwise conflicts may occur .

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 “master” and the second is the “slave”. 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 other vendor ’ s SCSI controller card, please refer to their respective documentations on how to install the required SCSI drivers.
ASUS P/I-P55T2P4S User’ s Manual 38 IV . BIOS SOFTW ARE IV . BIOS (Standard CMOS) For IDE hard disk drive setup, you can: • Use the Auto setting for detection during bootup. • Use the IDE HDD AUTO DETECTION in the main menu to automatically enter the drive specifications. • Enter the specifications yourself manually by using the “User” 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. Auto detection of hard disks on bootup For each field: Primary Master , Primary Slave, Secondary Master , and Secondary Slave, you can select Auto under the TYPE and MODE fields. This will enable auto detection of your IDE drives during bootup. This will allow you to change your hard drives (with the power of f) and then power on without having to reconfigure your hard drive type. If you use older hard drives which do not support this feature, then you must configure the hard drive in the standard method as described above by the "User" option. NOTE: After the IDE hard disk drive information has been entered into BIOS, new IDE hard disk drives must be partitioned (such as with FDISK) and then formatted before data can be read from and write on. Primary IDE hard disk drives must have its partition set to active (also possible with FDISK).

Setup default setting for this field is Enabled . A complete test of the system is done on each test. HDD Sequence SCSI/IDE First 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 This field determines where the system looks first for an operating system. Options are C,CDROM,A; CDROM,C,A; A,C; C,A The setup default setting is to check first the hard disk and then the floppy drive, that is, C, A . Boot Up Floppy Seek When enabled, the BIOS will seek the floppy “A” drive one time. By setup default, this field is set to Disabled. Floppy Disk Access Control This allows protection of files from the computer system to be copied to floppy drives by allowing the setting of Read Only to only allow reads from the floppy but not writes. The setup default R/W allows both reads and writes. IDE HDD Block Mode Sectors 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. By setup default, this field is set to HDD MAX, other selections are Dis- abled 2, 4, 8, 16, and 32 . Security Option 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. PS/2 Mouse Function Contr ol The default of Auto allows the system to detect a PS/2 Mouse on bootup. If de- tected, IRQ12 will be used for the PS/2 Mouse. IRQ12 will be reserved for expan- sion cards if a PS/2 Mouse is not detected. Disabled will reserve IRQ12 for expan- sion cards and therefore the PS/2 Mouse will not function.

ASUS P/I-P55T2P4S User’ s Manual 55 (Flash Memory W riter) 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 ’ 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 motherboard’ 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 (DMICFG.EXE) must be ran 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, “REM” HIMEM.SYS in the CONFIG.SYS, or press <F5> during bootup to bypass your AUTOEXEC.BA T and CONFIG.SYS files.

These utilities are used for hard disk drives only and will have no ef fect on other non-disk SCSI de- vices. Format Disk - is a SCSI low-level formatting utility . In general, SCSI hard drive have already been low-level formatted when you get them, so you generally should not need to use this function. V erify Media - scans the selected drive media for defects, notifies you of any found and gives you the option of reassigning bad blocks so that data will not be written to them. This is only necessary if you suspect that your SCSI disk drive has a problem. VI. ADAPTEC SCSI SELECT VI. SCSI SELECT (Configuring Adapter)

62 ASUS P/I-P55T2P4S User ’ s Manual VI. ADAPTEC EZ-SCSI UTILITY 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 ’ 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. VI. EZ-SCSI UTILITY (T roubleshooting)
ASUS P/I-P55T2P4S User’ s Manual 63 VI. ADAPTEC EZ-SCSI UTILITY VI. 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 Windows95 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 r ed 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.
64 ASUS P/I-P55T2P4S User ’ s Manual VI. ADAPTEC EZ-SCSI UTILITY If I am running under Windows95, do I need lines for the Adaptec real 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 HP’ 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 doesn’t 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 P/I-P55T2P4S User’ s Manual 65 VI. ADAPTEC EZ-SCSI UTILITY VI. 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.
66 ASUS P/I-P55T2P4S User ’ s Manual VI. ADAPTEC EZ-SCSI UTILITY 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, Iomega’ 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. VI. EZ-SCSI UTILITY (Formatting)
ASUS P/I-P55T2P4S User’ s Manual 67 VI. ADAPTEC EZ-SCSI UTILITY VI. 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 BIOS—that is, if the host adapter does not have a BIOS or if its BIOS is not en- abled. If the disk device is contr olled 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 ar get is the device’ 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 .
