7. At power on, hold down <Delete> to enter BIOS Setup. Follow the instructions in Chapter 4.
Powering off the computer
You must first exit the operating system and shut down the system before switching off the power. For ATX power supplies, you can press the ATX power switch after exiting or shutting down the operating system. If you use Windows 95/98/2000/XP, click the Start button, click Shut Down, then click the OK button to shut down the computer. The power supply should turn off after Windows shuts down.
The message You can now safely turn off your computer does not appear when shutting down with ATX power supplies.
Chapter 3: Powering up
This chapter tells how to change system settings through the BIOS Setup menus. Detailed descriptions of the BIOS parameters are also provided.
Managing and updating your BIOS
4.1.1 Using the computer system for the first time
It is recommended that you save a copy of the original motherboard BIOS along with a Flash Memory Writer utility (AFLASH.EXE) to a bootable floppy disk in case you need to reinstall the BIOS later. AFLASH.EXE is a Flash Memory Writer 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. To 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. Larger numbers represent a newer BIOS file. 1. Type FORMAT A:/S at the DOS prompt to create a bootable system disk. DO NOT copy AUTOEXEC.BAT and CONFIG.SYS to the disk. 2. Type COPY D:\AFLASH\AFLASH.EXE A:\ (assuming D is your CD-ROM drive) to copy AFLASH.EXE to the boot disk you created.
AFLASH works only in DOS mode. It does not work in the DOS prompt within Windows, and does not work with certain memory drivers that may be loaded when you boot from the hard drive. It is recommended that you reboot using a floppy disk.
3. Reboot the computer from the floppy disk.
BIOS setup must specify Floppy as the first item in the boot sequence.
4. In DOS mode, type A:\AFLASH <Enter> to run AFLASH.
If the word unknown appears 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 Writer utility.
5. Select 1. Save Current BIOS to File from the Main menu and press <Enter>. The Save Current BIOS To File screen appears.
6. Type a filename and the path, for example, A:\XXX-XX.XXX, then press <Enter>.
Chapter 4: BIOS Setup
4.1.2 Updating BIOS procedures
Update the BIOS only if you have problems with the motherboard and you are sure that the new BIOS revision will solve your problems. Careless updating may result to more problems with the motherboard!
1. Download an updated ASUS BIOS file from the Internet (WWW or FTP) (see ASUS CONTACT INFORMATION on page x for details) and save to the boot floppy disk you created earlier. 2. Boot from the floppy disk. 3. At the A:\ prompt, type AFLASH and then press <Enter>. 4. At the Main Menu, type 2 then press <Enter>. The Update BIOS Including Boot Block and ESCD screen appears. 5. Type the filename of your new BIOS and the path, for example, A:\XXX-XX.XXX, then press <Enter>. To cancel this operation, press <Enter>.
6. When prompted to confirm the BIOS update, press Y to start the update.
7. The utility starts to program the new BIOS information into the Flash ROM. The boot block is updated automatically only when necessary. This minimizes the possibility of boot problems in case of update failures. When the programming is done, the message Flashed Successfully appears.
8. Follow the onscreen instructions to continue.
If you encounter problems while updating the new BIOS, DO NOT turn off the system because this may cause boot problems. Just repeat the process, and if the problem persists, load the original BIOS file you saved to the boot disk. If the Flash Memory Writer utility is not able to successfully update a complete BIOS file, the system may not boot. If this happens, call the ASUS service center for support.
BIOS Setup program
This motherboard supports a programmable EEPROM that you can update using the provided utility described in section 4.1 Managing and updating your BIOS. Use the BIOS Setup program when you are installing a motherboard, reconfiguring your system, or prompted to Run Setup. This section explains how to configure your system using this utility. Even if you are not prompted to use the Setup program, you may want to change the configuration of your computer in the future. For example, you may want to enable the security password feature or make changes to the power management settings. This requires you 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. Press <Delete> during the Power-On Self Test (POST) to enter the Setup utility, otherwise, POST continues with its test routines. If you wish to enter Setup after POST, restart the system by pressing <Ctrl> + <Alt> + <Delete>, or by pressing the reset button on the system chassis. You can also restart by turning the system off and then back on. Do this last option only if the first two failed. The Setup program is 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.
Note that a right pointer symbol (as shown on the left) appears to the left of certain fields. This pointer indicates that you can display a sub-menu from this field. A sub-menu contains additional options for a field parameter. To display a sub-menu, move the highlight to the field and press <Enter>. The submenu appears. Use the legend keys to enter values and move from field to field within a sub-menu as you would within a menu. Use the <Esc> key to return to the main menu. Take some time to familiarize yourself with the legend keys and their corresponding functions. Practice navigating through the various menus and sub-menus. If you accidentally make unwanted changes to any of the fields, use the set default hot key <F5> to load the Setup default values. While moving around through the Setup program, note that explanations appear in the Item Specific Help window located to the right of each menu. This window displays the help text for the currently highlighted field.
When you enter the Setup program, the following screen appears.
System Time [XX:XX:XX]
Sets the system to the time that you specify (usually the current time). The format is hour, minute, second. Valid values for hour, minute and second are Hour: (00 to 23), Minute: (00 to 59), Second: (00 to 59). Use the <Tab> or <Shift> + <Tab> keys to move between the hour, minute, and second fields.
System Date [XX/XX/XXXX]
Sets the system to the date that you specify (usually the current date). The format is month, day, year. Valid values for month, day, and year are Month: (1 to 12), Day: (1 to 31), Year: (up to 2084). Use the <Tab> or <Shift> + <Tab> keys to move between the month, day, and year fields.

IrDA (Infrared Data Association). An internaltional organization that creates and promotes inter-operable, low cost, infrared data interconnection standards that support a walk-up, point-to-point model. The IrDA protocol 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 World Wide Web 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. LAN (Local Area Network). A network technology designed to connect computers that are separated by a short distance. The local group of linked computers are normally connected to a single server. See also WAN (Wide Area Network) 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. OS (Operating System). The software that controls the overall operation of a computer system. The OS tasks include memory allocation, input and output distribution, interrupt processing, job scheduling, and various other duties. PC100/PC133. 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 Interconnect 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 furthermore, 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 Test). 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 motherboard 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 ATX motherboards. RAM (Random Access Memory). The computers primary storage area used to write, store, and retrieve information and program instructions which are passed to the CPU for processing. 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 off, or if power glitches occur. See also DRAM and SDRAM. ROM (Read Only Memory). An integrated circuit chip containing program and data that can be accessed and read but not modified. 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 covers 10MBytes/sec to 160MBytes/sec data rates. 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. SIR (Serial IrDA). A SIR specification defines a short-range infrared asynchronous serial transmission mode with one stat bit, eight data bits and one stop bit. The maximum data rate is 115.2Kbps. SPD for SDRAM module. Serial Presence Detect (SPD) is most like an ID detect for SDRAM module, it uses an EEPROM component on a DIMM 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 organization and timing parameters.
System Disk. A system disk contains the core file of an operating system and is used to boot up the operating system. TCP/IP (Transmission Control Protocol/Internet Protocol). The communications protocol 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-n-Play computer peripherals (such as keyboard, mouse, joystick, scanner, printer, modem, and monitor) to share bandwidth through a host scheduled token-based protocols. 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 40 times the transfer rate compared to USB 1.0 and competes with the 1394 standard. WAN (Wide Area Network). A geographically dispersed network formed by linking several computers or Local Area Networks (LANs) together over long distances.
