Chapter 3
Award BIOS
This chapter tellshowtoconfigurethe system parameters. You may update your
BIOS via AWARD Flash Utility.
Important: Because the BIOS code is the most
often changed part of the mainboard design, the
BIOS information contained in this chapter
(especiallythe Chipset Setup parameters) may be a
little different compared to the actual BIOS that
came with your mainboard.
3.1 Entering the Award BIOS Setup Menu
The BIOS setup utility is a segment of codes/routines residing in the BIOS Flash
ROM. This routine allows you to configure the system parameters and save the
configuration into the 128 byte CMOS area, (normally in the RTC chip or directly
in the main chipset). To enter the BIOS Setup, press during POST
(Power-On Self Test). The BIOS Setup Main Menu appears as follows.

your system supports. These parameters are Size,
Number of Cylinder, Number of Head, Start Cylinder for
Pre-compensation, Cylinder number of Head Landing

Warning: The default memory timing setting is
60ns to get the optimal performance. Because
the specification limitation of INTEL TX chipset ,
70ns SIMM can only be used with CPU external

The Leadoff means the timing of first memory cycle in
the burst read or write. Actually, this item controls only
page miss read/write leadoff timing and the clocks of
RAS precharge and RAS to CAS delay. The four digital
represent Read Leadoff/ Write Leadoff/ RAS
Precharge/ RAS to CAS delay. For example, default is
10/6/3/3, which means you have 10-x-x-x DRAM page
miss read and 6-x-x-x DRAM write, with 3 clocks RAS
precharge and 3 clocks RAS to CAS delay.

Read Burst means to read four continuous memory
cycles on four predefined addresses from the DRAM.
The default value is x222/x333 for 60ns EDO or FPM
(Fast Page Mode) DRAM. Which means the 2nd,3rd
and 4th memory cycles are 2 CPU clocks for EDO and 3

For some old I/O chips, after the execution of an I/O
command, the device requires a certain amount of time
(recovery time) before the execution of the next I/O
command. Because of new generation CPU and
mainboard chipset, the assertion of I/O command is
faster, and sometimes shorter than specified I/O
recovery time of old I/O devices. This item lets you
specify the delay of 8-bit I/O command by count of ISA
bus clock. If you find any unstable 8-bit I/O card, you
may try to extend the I/O recovery time via this item.

Clock Throttling means at the Doze/Standby state, the
CPU clock count in a given time (not the frequency) is
reduced to the ratio specified in this parameter.
Actually, the period per CPU clock is not changed. For
example, a 66MHz CPU clock remains the same 30ns
clock period when system goes into Doze/Suspend.
The chipset generates the STPCLK (stop clock) signal
periodically to prevent CPU for accepting clock from
clock generator. For full power on, the CPU can receive
66M count in one second. If the Slow Clock Ratio is set
to 50%, the CPU will only receive 33M clock count in
one second. This will effectively reduce CPU speed as
well as CPU power.

If your ISA card is not PnP compatible and requires
special memory space to support its function, specify
the memory size in this parameter to inform the PnP
BIOS to reserve the specified memory space for
installed legacy ISA card.
3.7 Load Setup Defaults
The "Load Setup Defaults" option loads optimized settings for optimum system
performance. Optimal settings are relatively safer than the Turbo settings. We
recommend you to use the Optimal settings if your system has large memory
size and fully loaded with add-on card (for example, a file server using doublesided 8MB SIMM x4 and SCSI plus Network card occupying the PCI and ISA
slots).
3-28
AWARD BIOS
Optimal is not the slowest setting for this mainboard. If you need to verify a
unstable problem, you may manually set the parameter in the "BIOS Features
Setup" and "Chipset Features Setup" to get slowest and safer setting.
3.8 Load Turbo Defaults
The "Load Turbo Defaults" option gives better performance than Optimal values.
However, Turbo values may not be the best setting of this mainboard but these
values are qualified by the AOpen RD and QA department as the reliable settings
especially if you have limited loading of add-on card and memory size (for
example, a system that contains only a VGA/Sound card and two SIMMs).
To attain the best system performance, you may manually set the parameters in
the "Chipset Features Setup" to get proprietary setting. Make sure that you know
and understand the functions of every item in Chipset Setup menu. The
performance difference of Turbo from Optimal is normally around 3% to 10%,
depending on the chipset and the application.

asterisks on the password screen box.
2. After typing the password, press.
3. At the next prompt, re-type your password and press again to confirm the

If your system has an IDE hard drive, you can use this function to detect its

This routine only detects one set of parameters for your IDE hard drive. Some

formatted using different parameters than those detected, you have to enter the
parameters manually. If the parameters listed do not match the ones used to
format the disk, the information on that disk will not be accessible. If the autodetected parameters displayed do not match those that used for your drive,
ignore them. Type N to reject the values and enter the correct ones manually
from the Standard CMOS Setup screen.

The BIOS Flash utility allows you to upgrade the system BIOS. To get the
AOpen Flash utility and the upgrade BIOS file, contact your local distributor or
visit our homepage at http://www.aopen.com.tw. Please make sure that you
have the correct BIOS ready, the BIOS filename is normally like AP5TR110.BIN,
which means model AP5T BIOS revision 1.10.
There are two useful programs, Checksum utility CHECKSUM.EXE and AOpen
Flash utility AOFLASH.EXE. Follow the procedures below to upgrade your
BIOS.
[CHECKSUM.EXE]
This utility will help you to determine if the BIOS has been downloaded correctly
or not.
1. Execute
C:> CHECKSUM Biosfile.bin
Biosfile.bin is the filename of the BIOS code.
2. The utility will show "Checksum is ssss".
3. Compare the "ssss" with original checksum posted on Web or BBS. If they
are different, please do not proceed any further and try to download the BIOS
again.
[AOFLASH.EXE]
This utility will try to check the mainboard model, BIOS version and Super/Ultra
IO chip model. To ensure the correct BIOS file for the correct mainboard and IO
chip. This utility will permanently replace your original BIOS content after
flashing.
1. Bootup the system from DOS prompt without loading any memory manager
(HIMEM, EMM386, QEMM386, ...).
2. Execute
C:> AOFLASH Biosfile.bin
Biosfile.bin is the filename of the BIOS code.
3. After loading the new BIOS code, the utility will prompt you to save original
BIOS code into your HDD or floppy. Please press "Y" to store it as
"BIOS.OLD".
3-38
AWARD BIOS
4. After the old BIOS has been successfully saved, press "Y" to replace BIOS.
5. DO NOT turn off the power during "FLASHING".
6. Reboot the system by turn off the power after "FLASHING".
7. Press "DEL" key to enter BIOS setup during POST.
8. Reload the "BIOS SETUP DEFAULT" and reconfigure other items as
previous set.
9. Save & Exit. Done!
Warning: DO NOT turn off the power during
"FLASHING". If the BIOS programming is not
successfully finished, the system will not be boot
again, and you may need to physically replace the
BIOS chip.
Tip: You may load back original BIOS "BIOS.OLD" by
the same procedure.
