4.3 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, S4, and S5 sleep mode (no power to CPU, DRAM in slow
refresh, power supply in reduced power mode).

The USBPWR12 jumper is for the rear USB ports. The USBPWR34
and USBPWR56 jumpers are for the internal USB connectors that
you can connect to additional USB ports.

• The motherboard provides 0.5A for each USB port and 1.5A for all
devices requiring +5VSB power. To use the USB device wake-up
feature, the total +5VSB power for all connected devices must not
exceed 1.5A.

• The total current consumed must NOT exceed the power supply
capability (+5VSB), whether under normal condition or in sleep mode.

• Make sure to set the jumpers to +5VSB if you want to wake up the
system from S3, S4, and S5 sleep mode.

from a floppy disk that contains the BIOS file, in case the current BIOS on
the motherboard fails or gets corrupted.

• Prepare the floppy disk that contains the motherboard BIOS

(A7VT.BIN) before proceeding with the BIOS update process.

• If you have saved a copy of the original motherboard BIOS to a
bootable floppy disk, you may also use this disk to restore the BIOS.

To recover the BIOS from a floppy disk:

1. Boot the system.

2. When a corrupted BIOS is detected, the following message appears.

Bad BIOS checksum. Starting BIOS recovery...

Checking for floppy...

3. Insert a floppy disk that contains the original, or the latest, BIOS file
for this motherboard (A7VT.BIN). If the BIOS file that you downloaded
from the ASUS website has a different filename (e.g.
A7VT_1001.001). Rename it to A7VT.BIN. The BIOS update process
continues when the A7VT.BIN is found.

Bad BIOS checksum. Starting BIOS recovery...

Checking for floppy...

Floppy found!

Reading file “a7vt.bin”. Completed.

Start flashing...

DO NOT shut down or reset the system while updating the BIOS!
Doing so may cause system boot failure!

4. When the BIOS update process is complete, reboot the system.

5.1.4 ASUS Update

The ASUS Update is a utility that allows you to update the motherboard
BIOS in Windows® environment. This utility is available in the support CD
that comes with the motherboard package. ASUS Update requires an
Internet connection either through a network or an Internet Service
Provider (ISP).

Go to section “3.3.2 ASUS Update” for details on how to update the
motherboard BIOS using ASUS Update.

Chapter 5: BIOS information

5.2 BIOS Setup program

This motherboard supports a programmable Flash ROM that you can
update using the provided utility described in section

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.

“5.1 Managing and

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.

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.
