ASUS A7A266 User ’ s Manual 29 3. HARDW ARE SETUP Expansion Cards 3. H/W SETUP Expansion Cards 3.7.2 Assigning IRQs for Expansion Cards Some expansion cards need an IRQ to operate. Generally , an IRQ must be exclu- sively 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. If your motherboard has PCI audio onboard, an additional IRQ will be used. If your moth- erboard also has MIDI enabled, another IRQ will be used, leaving 4 IRQs free. IMPOR T ANT : If using PCI cards on shared slots, make sure that the drivers sup- port “ Share IRQ ” or that the cards do not need IRQ assignments. Conflicts will arise between the two PCI groups that will make the system unstable or cards inop- erable. The following table lists the default IRQ assignments for standard PC devices.

4. BIOS SETUP 4.1 Managing and Updating Y our BIOS 4.1.1 Upon First Use of the Computer System It is recommended that you save a copy of the original motherboard BIOS along with a Flash Memory W riter utility (AFLASH.EXE) to a bootable floppy disk in case you need to reinstall the BIOS later . AFLASH.EXE is a Flash Memory W riter utility that updates the BIOS by uploading a new BIOS file to the programmable flash ROM on the motherboard. This file works only in DOS mode. T o determine the BIOS version of your motherboard, check the last four numbers of the code displayed on the upper left-hand corner of your screen during bootup. Lar ger numbers represent a newer BIOS file. 1. T ype FORMA T A:/S at the DOS prompt to create a bootable system floppy disk. DO NOT copy AUTOEXEC.BA T & CONFIG.SYS to the disk. 2. T ype COPY D:\AFLASH\AFLASH.EXE A:\ (assuming D is your CD- ROM drive) to copy AFLASH.EXE to the just created boot disk. NOTE: AFLASH works only in DOS mode. It will not work with DOS prompt in W indows and will not work with certain memory drivers that may be loaded when you boot from your hard drive. It is recommended that you reboot using a floppy . 3. Reboot your computer from the floppy disk. NOTE: BIOS setup must specify “Floppy ” as the first item in the boot sequence. 4. In DOS mode, type A:\AFLASH <Enter> to run AFLASH. IMPORT ANT! If “ unknown” is displayed after Flash Memory:, the memory chip is either not programmable or is not supported by the ACPI BIOS and therefore, cannot be programmed by the Flash Memory W riter utility .

ASUS A7A266 User ’ s Manual 51 4. BIOS SETUP 4. BIOS SETUP 4.2 BIOS Setup Program This motherboard supports a programmable EEPROM that can be updated using the provided utility as described in 4.1 Managing and Updating Y our BIOS . The utility is used if you are installing a motherboard, reconfiguring your system, or prompted to “ Run Setup ”. This section describes how to configure your system using this utility . Even if you are not prompted to use the Setup program, at some time in the future you may want to change the configuration of your computer . For example, you may want to enable the Security Password Feature or make changes to the power management settings. It will then be necessary to reconfigure your system using the BIOS Setup program so that the computer can recognize these changes and record them in the CMOS RAM of the EEPROM. The EEPROM on the motherboard stores the Setup utility . When you start up the computer , the system provides you with the opportunity to run this program. This appears during the Power -On Self T est (POST). Press <Delete> to call up the Setup utility . If you are a little bit late in pressing the mentioned key , POST will continue with its test routines, thus preventing you from calling up Setup. If you still need to call Setup, restart the system by pressing <Ctrl> <Alt> <Delete>, or by press- ing the Reset button on the system chassis. 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. The Setup program has been designed to make it as easy to use as possible. It is a menu-driven program, which means you can scroll through the various sub-menus and make your selections among the predetermined choices. To access the BIOS Setup program, press the <Delete> key after the computer has run through its POST.

ASUS A7V133 User ’ s Manual 93 7 . APPENDIX Glossary 7. APPENDIX 7.1 Glossary 1394 1394 is the IEEE designation for the high performance serial bus at 12.5, 25 or 50MBytes/sec speeds. This serial bus defines both a back plane physical layer and a point-to-point cable-connected virtual bus. The primary application of the cable ver- sion is the integration of I/O connectivity at the back panel of personal computers using a low-cost, scalable, high-speed serial interface. The 1394 standard also pro- vides new services such as live connect/disconnect capability for external devices including disk drives, printers and hand-held peripherals such as scanners and cam- eras. This is a new standard to complement the slower USB interface and to compete with the more expensive SCSI interface. AC97 (Audio Codec '97) AC '97 is the next step in enabling PCs with audio quality comparable to consumer electronics devices. The specification defines new cost-ef fective options to help in- tegrate the components necessary to support next-generation auto-intensive PC ap- plications such as DVD, 3-D multiplayer gaming and interactive music. The speci- fication also defines new extensions supporting modem and docking to help both desktop and mobile manufacturers adopt these new technologies more quickly and cost-ef fectively . This specification uses software emulation to compete with the PCI SoundBlaster specification. ACPI (Advanced Configuration and Power Interface) The ACPI specification defines a cross-platform interface designed to support many operating systems. ACPI defines a flexible and abstract hardware interface that pro- vides a standard way to integrate power management features throughout a PC sys- tem, including hardware, operating system and application software. This enables the system to automatically turn ON and OFF peripherals such as CD-ROMs, net- work cards, hard disk drives, and printers, as well as consumer devices connected to the PC such as VCRs, TVs, phones, and stereos. W ith this technology , peripherals will also be able to activate the PC. For example, inserting a tape into a VCR can turn on the PC, which could then activate a lar ge-screen TV and high-fidelity sound system. AGP (Accelerated Graphics Port) An interface specification that enables high-performance 3D graphics on mainstream PCs. AGP was designed to offer the necessary bandwidth and latency to perform texture mapping directly from system memory . Bus Bus Frequency Bandwidth Data T ransfer Rate PCI 33MHz 33MHz 133MByte/sec AGP 1X 66MHz 66MHz 266MByte/sec AGP 2X 66MHz 133MHz 512MByte/sec AGP 4X 66MHz 266MHz 1024MByte/sec BIOS (Basic Input/Output System) BIOS is a set of routines that af fect how the computer transfers data between com- puter components, such as memory , disks, and the display adapter . The BIOS in- structions are built into the computer ’ s read-only memory . BIOS parameters can be configured by the user through the BIOS Setup program. The BIOS can be updated using the provided utility to copy a new BIOS file into the EEPROM. Bit (Binary Digit) Represents the smallest unit of data used by the computer . A bit can have one of two values: 0 or 1.
ASUS A7V133 User ’ s Manual 94 7. APPENDIX 7. APPENDIX Glossary Boot Boot means to start the computer operating system by loading it into system memory . When the manual instructs you to “ boot” your system (or computer), it means to turn ON your computer . “ Reboot” means to restart your computer . When using W in- dows 95 or later , selecting “ Restart” from “Start | Shut Down... ” will reboot your computer . Bus Master IDE PIO (Programmable I/O) IDE requires that the CPU be involved in IDE access and waiting for mechanical events. Bus master IDE transfers data to/from the memory without interrupting the CPU. Bus master IDE driver and bus master IDE hard disk drives are required to support bus master IDE mode. Byte (Binary T erm) One byte is a group of eight contiguous bits. A byte is used to represent a single alphanumeric character , punctuation mark, or other symbol. COM Port COM is a logical device name used by to designate the computer serial ports. Point- ing devices, modems, and infrared modules can be connected to COM ports. Each COM port is configured to use a different IRQ and address assignment. Concurrent PCI Concurrent PCI maximizes system performance with simultaneous CPU, PCI and ISA bus activities. It includes multi-transaction timing, enhanced write performance, a passive release mechanism and support for PCI 2.1 compliant delayed transac- tions. Concurrent PCI provides increased bandwidth, reduced system latencies, im- proves video and audio performance, and improves processing of host based appli- cations. CPU (Central Processing Unit) The CPU, sometimes called “ Processor , ” actually functions as the “brain ” of the computer . It interprets and executes program commands and processes data stored in memory . Currently , there are socket 370 (for Pentium III FC-PGA and Celeron- PPGA), socket 7 (for Pentium, AMD, Cyrix, IBM), slot 1 (for Pentium II and III), slot 2 (for Xeon), and slot A (for AMD) processors. Device Driver A device driver is a special set of instructions that allows the computer ’ s operating system to communicate with devices such as VGA, audio, printer , or modem. DOS (Disk Operating System) DOS is the foundation on which all other programs and software applications oper - ate, including W indows. DOS is responsible for allocating system resources such as memory , CPU time, disk space, and access to peripheral devices. For this reason, DOS constitutes the basic interface between you and your computer . DRAM (Dynamic Random Access Memory) There are several different types of DRAM such as, EDO DRAM (Extended Data Output DRAM), SDRAM (Synchronous DRAM), and RDRAM (Rambus DRAM). Flash ROM The flash ROM is designed to be a resident program and can be updated by a spe- cific programming method. Normally , the flash ROM is used for system BIOS which initiates hardware devices and sets up necessary parameters for the OS. Since the contents of flash ROM can be modified, users are able to update the BIOS by them- selves. IDE (Integrated Drive Electronics) IDE devices integrate the drive control circuitry directly on the drive itself, elimi- nating the need for a separate adapter card (in the case for SCSI devices). UltraDMA/ 33 IDE devices can achieve up to 33MB/Sec transfer .
ASUS A7V133 User ’ s Manual 95 7 . APPENDIX Glossary 7. APPENDIX LPT Port (Line Printer Port) Logical device name reserved by DOS for the computer parallel ports. Each LPT port is configured to use a dif ferent IRQ and address assignment. MMX A set of 57 new instructions based on a technique called Single Instruction, Multiple Data (SIMD), which is built into the new Intel Pentium PP/MT (P55C) and Pentium II (Klamath) CPU as well as other x86-compatible microprocessors. The MMX in- structions are designed to accelerate multimedia and communications applications, such as 3D video, 3D sound, video conference. OnNow The OnNow design initiative is a comprehensive, system-wide approach to system and device power control. OnNow is a term for PC that is always ON but appears OFF and responds immediately to user or other requests. The OnNow design initia- tive involves changes that will occur in the Microsoft W indows operating system, device drivers, hardware, and applications, and also relies on the changes defined in the Advanced Configuration and Power Interface (ACPI) specification. PC100 SDRAM is Intel's goal is to ensure that memory subsystems continue to support evolving platform requirements and to assure that memory does not become a bottle- neck to system performance. It is especially important to ensure that the PC memory roadmap evolves together with the performance roadmaps for the processors, I/O and graphics. PCI Bus (Peripheral Component Inter connect Local Bus) PCI bus is a specification that defines a 32-bit data bus interface. PCI is a standard widely used by expansion card manufacturers. PCI Bus Master The PCI Bus Master can perform data transfer without local CPU help and further - more, the CPU can be treated as one of the Bus Masters. PCI 2.1 supports concur - rent PCI operation to allow the local CPU and bus master to work simultaneously . Plug and Play BIOS The ISA bus architecture requires the allocation of memory and I/O address, DMA channels and interrupt levels among multiple ISA cards. However , configuration of ISA cards is typically done with jumpers that change the decode maps for memory and I/O space and steer the DMA and interrupt signals to different pins on the bus. Further , system configuration files may need to be updated to reflect these changes. Users typically resolve sharing conflicts by referring to documentation provided by each manufacturer . For the average user , this configuration process can be unreli- able and frustrating. Plug and play (PnP) BIOS eliminates the ISA add-on card hard- ware conflict problem. The PnP BIOS uses a memory block to define and remember each card's configuration, which allows the user to change the card's IRQs and DMA in BIOS either automatically or manually . POST (Power On Self T est) When you turn ON the computer , it will first run through the POST , a series of software-controlled diagnostic tests. The POST checks system memory , the mother - board circuitry , the display , the keyboard, the diskette drive, and other I/O devices. PS/2 Port PS/2 ports are based on IBM Micro Channel Architecture. This type of architecture transfers data through a 16-bit or 32-bit bus. A PS/2 mouse and/or keyboard may be used on A TX motherboards. RDRAM (Rambus DRAM) Developed by Rambus, Inc., this type of memory can deliver up to 1.6GB of data per second. RDRAM is the first interface standard that can be directly implemented on high performance VLSI components such as, CMOS DRAMs, memory control- lers, and graphics/video ICs.
ASUS A7V133 User ’ s Manual 96 7. APPENDIX 7. APPENDIX Glossary ROM (Read Only Memory) ROM is nonvolatile memory used to store permanent programs (called firmware) used in certain computer components. Flash ROM (or EEPROM) can be repro- grammed with new programs (or BIOS). SCSI (Small Computer System Interface) High speed multi-threaded I/O interface defined by the X3T9.2 committee of the American National Standards Institute (ANSI) for connecting many peripheral de- vices. The standard started from 10MBytes/sec to 160MBytes/sec available today . SDRAM (Synchronous DRAM) The SDRAM features a fully synchronous operation referenced to a positive edge clock whereby all operations are synchronized at a clock input which enables the coexistence of high performance and a simple user interface. SDRAM takes memory access away from the CPU's control; internal registers in the chips accept the re- quest, and let the CPU do something else while the data requested is assembled for the next time the CPU talks to the memory . As they work on their own clock cycle, the rest of the system can be clocked faster . There is a version optimized for video cards, and main memory for motherboards. SPD for SDRAM module Serial Presence Detect (SPD) is most like an ID detect for SDRAM module, it using a EEPROM component on DIMM module for storing module configuration infor - mation inside. The Serial Presence Detect function is implemented using a 2048 bit EEPROM component. This nonvolatile storage device contains data programmed by the DIMM manufacturer that identifies the module type and various SDRAM organization and timing parameters. SSE (Streaming SIMD Extensions) A set of new instructions added to existing architectures that enables a better visual experience with an accelerated 3D geometry pipeline and support for new applica- tions, such as real-time video encoding and speech recognition. System Disk A system disk contains the core file of an operating system and is used to boot up the operating system. UltraDMA Ultra DMA/33 is a "synchronous DMA" protocol designed by Intel. This function is included into Intel's PIIX4 chipset. The traditional IDE transfer only uses one edge of the data stroke as the data transfer . Ultra DMA/33 uses both edges of data strobe when the data is transferred. Hence, the data transfer rate is double of the PIO mode 4 or DMA mode 2 (16.6MB/s x2 = 33MB/s) on A T A-2 devices. Ultra A T A/66, also known as Ultra DMA/66, is an extension of current Ultra A T A/ 33 interface. This new high-speed interface has doubled the Ultra A T A/33 burst data transfer rate to 66.6 Mbytes/sec and maximized disk performance under current PCI local bus environment USB (Universal Serial Bus) A 4-pin serial cable bus that allows up to 127 plug and play computer peripherals such as keyboard, mouse, joystick, scanner , printer , modem, and monitor to share a bandwidth through a host scheduled token based protocol. This allows attaching or detaching while the host and other peripherals are in operation. Supports synchro- nous and asynchronous transfer types over the same set of wires up to 12Mbit/sec. USB 2.0 provides twice the transfer rate compared to USB 1.0 and competes with the 1394 standard. W ake-On-LAN Computer will automatically wake-up upon receiving a wake-up packet through a Network interface when it is under power soft-of f, suspend or sleep mode.
