Chapter 3: Motherboard information

3.5 System memory

The motherboard has two Double Data Rate (DDR) DIMM sockets that
supports up to 2GB unbuffered non-ECC PC2100/1600 DDR DIMMs.

A DDR DIMM has the same physical dimensions as an SDR DIMM, but it
has a 184-pin footprint compared to the 168-pin of the SDR DIMM. Also, a
DDR DIMM is single notched while an SDR DIMM is double notched.
Therefore, a DDR DIMM is not backward compatible with SDR, and should
be installed only in a socket specially designed for DDR DIMMs.

3.8 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/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/100/66 slave device (hard disk drive) and
the black connector to the UltraDMA/100/66 master device. It is
recommended that you connect non-UltraDMA/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/100/66 devices, purchase another UltraDMA/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.

NOTES

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 UltraDMA/100/66 IDE devices, use an 80-conductor IDE cable. The
UltraDMA/66 cable included in the motherboard package also supports
UltraDMA/100.

BIOS Information

55

4.1 Managing and updating the BIOS

4.1.1 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 (AFLASH.EXE) to a bootable
floppy disk in case you need to reinstall the BIOS later. 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.

NOTE

AFLASH works only in DOS mode. It does not work in the DOS prompt
within Windows, and 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.

NOTE

BIOS setup must specify “Floppy” as the first item in the boot sequence.

56

Chapter 4: BIOS information

4. In DOS mode, type A:\AFLASH <Enter> to run AFLASH.

IMPORTANT

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.

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>.

4.1.2 Updating BIOS procedures

CAUTION!

Update the BIOS only if you have problems with the motherboard and
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>.

6. When prompted to confirm the BIOS update, press Y to start the
update.

58

Chapter 4: BIOS information

7. The utility starts to program the new BIOS information into the Flash
ROM. The boot block is updated automatically only when necessary.
This minimizes the possibility of boot problems in case of update
failures. When the programming is done, the message

Successfully”

appears.

“Flashed

8. Follow the onscreen instructions to continue.

WARNING!

If you encounter problems while updating the new BIOS, DO NOT turn
off the system because 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, the system may not boot. If
this happens, call the ASUS service center for support.

ASUS Terminator P4 Barebone System

4.2 BIOS Setup program

This motherboard supports a programmable EEPROM 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 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.

“4.1 Managing and

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 menu-driven program, which means you can scroll through the various
sub-menus and make your selections among the predetermined choices.

NOTE

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.
