Jumpers

USB device wake-up (3-pin USBPWR_12,USBPWR_34,USBPWR_56) Set these jumpers to +5V to wake up the computer from S1 sleep mode (CPU stopped, DRAM refreshed, system running in low power mode) using the connected USB devices. Set to +5VSB to wake up from S3 sleep mode (no power to CPU, DRAM in slow refresh, power supply in reduced power mode). Both jumpers are set to pins 1-2 (+5V) by default because not all computers have the appropriate power supply to support this feature. The USBPWR_12 and USBPWR_34 jumpers are for the rear USB port. USBPWR_56 is for the internal USB header that you can connect to the front USB ports. This feature requires a power supply that can provide at least 2A on the +5VSB lead when these jumpers are set to +5VSB. Otherwise, the system does not power up. The total current consumed must NOT exceed the power supply capability (+5VSB) whether under normal condition or in sleep mode.

BIOS Information

This chapter gives information about the ASUS A7N8X Basic Input/Output System (BIOS).This chapter includes updating the BIOS using the ASUS AFLASH BIOS that is bundled with the support CD.
Managing and updating your BIOS
2.1.1 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 (AWDFLASH.EXE) to a bootable floppy disk in case you need to reinstall the BIOS later. AWDFLASH.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:\SOFTWARE\AWDFLASH\AWDFLASH.EXE A:\ (assuming D is your CD-ROM drive) to copy AWDFLASH.EXE to the boot disk you created.

Reboot the computer. To use AwardBIOS Flash Utility, press <Alt> + <F2> during POST to display the following screen.
The BIOS information in the above screen is for reference only. what you see on your screen may not be exactly the same as shown.
Insert the disk that contains the new BIOS file into the floppy drive. You will receive the error message, WARNING! Device not ready! if you proceed to step 5 without the disk in the drive.
5. Type the name of the new BIOS file, for example: AW0702.BIN then press <Enter>. The program asks if you want to save the previous BIOS. Select <Y> since it is advisable to back-up the original BIOS in case you need to reprogram it.
The program asks to save the previous BIOS to a separate file. Type a file name for the old bios and then press <Y>. The AWDFLASH program backsup the file.
AWDFLASH proceeds to check the new BIOS file and asks the user to program (flash) the new BIOS file to the motherboard.
Type <Y> and Press <Enter> to flash the new Bios file. NOTE: Do not shut off system power or unplug the supply during the flash process.
9. The BIOS flashes and displays the results. Press <F1> to restart.
2.1.2.2 Updating BIOS via Bootable Floppy Disk
1. Boot from the floppy disk. 2. At the A:\ prompt, type C:\ and then press <Enter>.
3. At the C:\ prompt, type AWDFLASH /qi BIOSFILE and then <Enter>. For example: AWDFLASH /qi aw0702.bin The AWDFLASH screen appears, and the BIOS file appears in the space, File Name to Program. 4. Type the name of the new BIOS file, for example: AW0702.BIN then press <Enter>. The program asks if you want to save the previous BIOS. Select <Y> since it is advisable to back-up the original BIOS in case you need to reprogram it. 5. Follow steps 6 to 9 in 2.1.2.1 Updating BIOS via Built-in Award BIOS Flash Utility.

BIOS Setup program

This motherboard supports a programmable FLASH ROM that you can update using the provided utility described in section 2.1 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 FLASH ROM. The FLASH ROM 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 menudriven program, which means you can scroll through the various sub-menus and make your selections among the predetermined choices.

Because the BIOS software is constantly being updated, the following BIOS setup screens and descriptions are for reference purposes only, and may not exactly match what you see on your screen.
