1.10 Jumpers
This section describes and illustrates the jumpers on the motherboard.
1. 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).
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 PRI_IDE, SEC_IDE)
This connector supports the provided UltraDMA100/66 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 UltraDMA100/66 slave device (hard disk drive) and
the black connector to the UltraDMA100/66 master device. It is
recommended that you connect non-UltraDMA100/66 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 UltraDMA100/66 devices, purchase another UltraDMA100/66
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.
For UltraDMA100/66 IDE devices, use an 80-conductor IDE cable.
NOTE: Orient the red markings
(usually zigzag) on the IDE
ribbon cable to PIN 1.

3. Chassis Alarm (4-1 pin CHASSIS1)
This lead is for a chassis designed with intrusion detection feature.
This requires an external detection mechanism such as a chassis
intrusion sensor or microswitch. When you remove any chassis
component, the sensor triggers and sends a high-level signal to this
lead to record a chassis intrusion event.
By default, the pins labeled “Chassis Signal” and “GND” are shorted
with a jumper cap. If you wish to use the chassis intrusion detection
feature, remove the jumper caps from the pins.

support CD.
ASUS P4BGV-MX Motherboard
2-1
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 viii). 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.

2.1.2 Using AFLASH to update the BIOS
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.
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.

2.2 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
