Chapter 1: Motherboard Information
1.11 Jumpers
This section describes and illustrates the jumpers on the motherboard.
USB device wake-up (3-pin USBPWR12,USBPWR34,USBPWR56)
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 USBPWR12 and USBPWR34 jumpers are for the rear USB ports.
USBPWR56 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 1A on the +5VSB
lead when these jumpers are set to +5VSB. Or, 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.

1.12 Connectors
This section describes and illustrates the connectors on the motherboard.
ATX power connectors (20-pin ATXPWR)
These connectors connect to an ATX 12V power supply. The plugs from the
power supply are designed to fit these connectors in only one orientation. Find
the proper orientation and push down firmly until the connectors completely fit.
A7V8X-X ATX Power Connectors
If you will need to replace the power supply in the future, make sure that your
new ATX 12V power supply can provide 8A on the +12V lead and at least 1A on
the +5-volt standby lead (+5VSB). The minimum recommended wattage is
230W, or 300W for a fully configured system. The system may become unstable
and may experience difficulty powering up if the power supply is inadequate.
USB headers (10-1 pin USB56)
If the USB 2.0 port connectors on the back panel are inadequate, two USB
headers (blue headers) are available for four additional USB port connectors.

connector to the UltraDMA/133/100/66 slave device (hard disk drive) and the
black connector to the UltraDMA/133/100/66 master device. It is
recommended that you connect non-UltraDMA/133/100/66 devices to the
secondary IDE connector. If you install two hard disks, you must configure
the second drive as a slave device by setting its jumper accordingly. Refer to
the hard disk documentation for the jumper settings. BIOS supports specific
device bootup. If you have more than two UltraDMA/133/100/66 devices,
purchase another UltraDMA/133/100/66 cable. You may configure two hard
disks to be both master devices with two ribbon cables – one for the primary
IDE connector and another for the secondary IDE connector.
Pin 20 on each IDE connector is removed to match the covered hole on the
UltraDMA cable connector. This prevents incorrect orientation when you
connect the cables.

go through the long process of booting from a diskette and using a DOS-based
utility. The EZ Flash is built-in the BIOS firmware so it is accessible by simply
pressing <Alt> + <F2> during the Power-On Self Tests (POST).
Follow these steps to update the BIOS using ASUS EZ Flash.
1. Download the latest BIOS file from the ASUS website (see ASUS contact
information on page x). Save the file to a floppy disk.
Write down the BIOS file name on a piece of paper. You need to type the exact
BIOS file name at the EZ Flash screen.
2. Reboot the computer.
3. To use EZ Flash, press <Alt> + <F2> during POST to display the following

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.
2.1.2 Using AFLASH to update the BIOS
Creating a bootable disk
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 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.
