Before you proceed
Take note of the following precautions before you install motherboard
components or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any
component.
2. Use a grounded wrist strap or touch a safely grounded object or to
a metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity.
3. Hold components by the edges to avoid touching the ICs on them.
4. Whenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.
5. Before you install or remove any component, ensure that the
ATX power supply is switched off or the power cord is
detached from the power supply. Failure to do so may cause
severe damage to the motherboard, peripherals, and/or
components.

1.10 Jumpers
This section describes and illustrates the jumpers on the motherboard.
1.
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 jumper is for the rear USB port. USBPWR34 and
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. 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.

1.11 Connectors
This section describes and illustrates the connectors on the motherboard.
1.
IDE connectors (40-1 pin IDE1, IDE2)
This connector supports the provided UltraDMA/133/100/66 IDE hard
disk ribbon cable. Connect the cable’s blue connector to the primary
(recommended) or secondary IDE connector, then connect the gray
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

2.1
Managing and Updating your BIOS
It is recommended that you save a copy of the motherboard’s original
BIOS to a bootable floppy disk in case you need to reinstall the original
BIOS later.
2.1.1 Using ASUS EZ Flash to update the BIOS
The ASUS EZ Flash feature allows you to easily update the BIOS without
having to 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 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.
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.

Chapter 2: BIOS Information
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>.
Updating the BIOS
Update the BIOS only if 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>.
ASUS A7S266-VM Motherboard

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.
When the programming is done, the message “Flashed Successfully”
appears.
8. Follow the onscreen instructions to continue.
DO NOT turn off the system while updating the BIOS. 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, call the ASUS service center for support.

BIOS Setup program
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.
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 submenus and make your selections among the predetermined choices.
Because the BIOS software is constantly being updated, the following
