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 mother- board, 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 there- fore, cannot be programmed by the Flash Memory W riter utility .

ASUS A7M266-D User ’ s Manual 45 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. NOTE: Because the BIOS software is constantly being updated, the following BIOS screens and descriptions are for reference purposes only and may not re- flect your BIOS screens exactly .

ASUS A7M266-D User ’ s Manual 93 7 . APPENDIX Glossary 7. APPENDIX 7.2 Glossary 1394 1394 is the IEEE designation for a high performance serial bus tht of fers data transfers at 100/ 200/400 Mbps. 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 version 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 provides new services such as live connect/ disconnect capability for external devices including disk drives, printers and hand-held pe- ripherals such as scanners and cameras. 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 electron- ics devices. The specification defines new cost-effective options to help integrate the compo- nents necessary to support next-generation auto-intensive PC applications such as DVD, 3-D multiplayer gaming and interactive music. The specification also defines new extensions sup- porting 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 operat- ing systems. ACPI defines a flexible and abstract hardware interface that provides a standard way to integrate power management features throughout a PC system, including hardware, operating system and application software. This enables the system to automatically turn ON and OFF peripherals such as CD-ROMs, network 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 large-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 Backup. A copy of a file, directory , or volume on a separate storage device from the original. This copy is for the purpose of data retrieval in case the original is accidentally erased, dam- aged, or destroyed. BIOS (Basic Input/Output System) BIOS is a set of routines that af fect how the computer transfers data between computer com- ponents, such as memory , disks, and the display adapter . The BIOS instructions 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 A7M266-D 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 indows 95 or later , select- ing “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 interrupt- ing 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. Cache Memory . A type of RAM that allows a faster from the CPU than a regular RAM. The cache memory eliminates the CPU wait state. When the CPU reads data from the main memory , a copy of this data is stored in the cache memory . The next time the same address, the data is transferred from the cache memory instead of from the main memory . CODEC (Compressor/Decompr essor) . A software component that translates video or au- dio between its uncompressed form and the compressed form in which it is stored. COM Port COM is a logical device name used by to designate the computer serial ports. Pointing de- vices, 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 transactions. Concurrent PCI provides increased bandwidth, reduced system latencies, improves video and audio performance, and improves processing of host based applications. 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 operate, includ- ing 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) A type of RAM that requires refresh cycles to prevent the loss of the data stored in it. There are several different types of DRAM such as, EDO DRAM (Extended Data Output DRAM), SDRAM (Synchronous DRAM), and RDRAM (Rambus DRAM) and DDR DRAM, (Double-Data Rate DRAM). Flash ROM non-volatile memory device that retains its data even when power is removed. This device is similar to EPROM, but unlike EPROM which can be erased only using an ultra-violet light, flash ROM can be electrically erased. Flash ROM is normally used for system BIOS, which initiates hardware devices and sets up necessary parameters for the OS. Since the flash ROM contents can be modified, users can easily update the BIOS..
ASUS A7M266-D User ’ s Manual 95 7 . APPENDIX Glossary 7. APPENDIX IDE (Integrated Drive Electr onics) IDE devices integrate the drive control circuitry directly on the drive itself, eliminating the need for a separate adapter card (in the case for SCSI devices). UltraDMA/33 IDE devices can achieve up to 33MB/Sec transfer . I/O (Input/Output) The data transfers from the input devices like a keyboard, mouse, or scanner , to the output devices like a printer or the monitor screen. I/O Address The specific memory location for a particular device. T wo devices cannot share the same I/O address space. IrDA (Infrared Data Association) An internaltional or ganization that creates and promotes inter -operable, low cost, infrared data interconnection standards that support a walk-up, point-to-point model. The IrDA proto- col is designed to support transmission of data between two devices over short-range point- to-point infrared at speeds between 9.6Kbps and 4Mbps. ISP (Internet Service Provider) A company that provides customer access to the Internet and the W orld W ide W eb for a fee. The ISP also provides Internet utilities and services like e-mail, newsgroup, weather reports, and a host of others. The user can connect to the ISP using a modem installed in the computer and connected to a phone line. 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 designed to accelerate multimedia and communications applica- tions, such as 3D video, 3D sound, video conference. Modem A device that allows a computer to talk to another computer through the phone system. Network An interconnected computer system linked by telephone wires, or other means. OnNow The OnNow design initiative is a comprehensive, system-wide approach to system and de- vice 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 initiative involves changes that will occur in the Microsoft W indows operating system, device drivers, hardware, and appli- cations, and also relies on the changes defined in the Advanced Configuration and Power Interface (ACPI) specification. PC100/133 This is an industry-standard designation for memory capacity as a measure of the speed of the memory bus. New platform requirements ensure that memory does not become a bottleneck to system performance. PCI Bus (Peripheral Component Inter connect Local Bus) PCI bus is a standard specification that defines a 32-bit data bus interface. PCI Bus Master The PCI Bus Master can perform data transfer without local CPU help and the CPU can be treated as one of the Bus Masters. PCI 2.1 supports concurrent PCI operation to allow the local CPU and bus master to work simultaneously . POST (Power On Self T est) Powering on the computer initiates the POST , a series of software-controlled diagnostic tests. The POST checks system memory , the motherboard circuitry , the display , the keyboard, the diskette drive, and other I/O devices
ASUS A7M266-D User ’ s Manual 96 7. APPENDIX 7. APPENDIX Glossary 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 controllers, and graphics/video ICs. RAM (Random Access Memory). The computer ’ s primary storage area used to write, store, and retrieve information and program instructions which are passed to the CPU for process- ing. The information in RAM can be repeatedly re-written with new data. Compared to other storage media like magnetic tape, floppy disk, and hard disk, RAM has an extraordinarily fast access rate. RAM, however , is volatile, which means that the data stored in it are lost when the system power is turned of f, or if power glitches occur . See also DRAM and SDRAM. 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 reprogrammed 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 devices. The standard started from 10MBytes/sec to 160MBytes/sec available today . SDRAM (Synchronous DRAM) A type of DRAM with access signals that are synchronized with the CPU clock, eliminating the delay associated with data transfers between the CPU and memory . SDRAM takes memory access away from the CPU control; internal registers in the memory accept the request, and lets the CPU do something else while the data requested is assembled for the next time the CPU talks to the memory . SPD for SDRAM module Serial Presence Detect (SPD) is most like an ID detect for SDRAM module, it using a EE- PROM component on DIMM module for storing module configuration information 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 or ganization and timing parameters. System Disk A system disk contains the core file of an operating system that boots up the operating system. TCP/IP (T ransmission Control Pr otocol/Internet Protocol). The communications proto- col used by the UNIX system and the Internet. TCP checks for lost packets, puts the data from multiple packets into the correct order , and requests that missing or damaged packets be resent. 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 synchronous and asynchronous transfer types over the same set of wires up to 12Mbit/sec. USB 2.0 provides twice the transfer rate com- pared 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-off, suspend or sleep mode.
