AOpen AX5T Specifications
Chapter 3
Award BIOS
This chapter tells how to configure the 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
(especially the 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.

that your system supports. These parameters are Size,
Number of Cylinder, Number of Head, Start Cylinder for
Pre-compensation, Cylinder number of Head Landing
Zone and Number of Sector per Track. The default
setting is Auto, which enables BIOS to automatically
detect the parameters of installed HDD at POST (PowerOn Self Test). If you prefer to enter HDD parameters
manually, select User. Select None if no HDD is
connected to the system.
The IDE CDROM is always automatically detected.
Tip: For an IDE hard disk, we recommend that

made possible through the Logical Block Address (LBA)
mode translation. The LBA is now considered as a
standard feature of current IDE hard disk on the market
because of its capability to support capacity larger than

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. The BIOS default value is 4 ISA clock. If set to
NA, the chipset will insert 3.5 system clocks.

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

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 double-sided 8MB SIMM x4 and SCSI plus Network card
occupying the PCI and ISA slots).
3-27
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.

3.16 Suspend to Hard Drive
Suspend to Hard Drive saves your current work (system status, memory and

Next time, when power is on, you can resume your original work directly from
hard disk within few second without go through the Win95 booting process
and run your application again. If your memory is 16MB, normally, you need
to reserve at least 16MB HDD space to save your memory image. Note that
you have to use VESA compatible PCI VGA (AOpen PV60/PT60), Sound
Blaster compatible sound card (AOpen AW32 or MP32) for Suspend to Hard
Drive to work properly. Of course, we recommend to use AOpen products for
best compatibility.
To use Suspen to Hard Drive:
1. Go into BIOS setup, Power Management
Suspend Mode Option, select
Suspend to Drive.
2. Use utility ZVHDD to create a hidden file in your hard disk drive. This file is
used to save your system status and memory image. Just type:
C:>ZVHDD /c /file
3. Push suspend switch or use Win95 Suspend icon to force system goes
into Suspend to Hard Drive mode and then turn system power off by
power switch of your power supply.
4. Next time you turn on your system, it will resume to your original work
automatically.
3.17 Modem Wake Up
The Modem Wake Up discussed here is to wakeup from true power off
(identified by fan of power supply is off), This mainboard still supports
traditional green PC suspend mode but it is not discussed here.
With the help ATX soft power On/Off, it is possible to have system totally
power off (The traditional suspend mode of power management function does
not really turn off the system power supply), and wakeup to automatically
answer a phone call such as answering machine or to send/receive fax. You
may identify the true power off by checking fan of your power supply. Both
external box modem and internal modem card can be used to support Modem
Wake Up, but if you use external modem, you have to keep the box modem
always power-on. AOpen AX5T/AX58 and internal modem card implement
special circuit (patent applied) and make sure the modem card works properly
3-36
AWARD BIOS
without any power. We recommend you choose AOpen modem card (F34 or
MP32) for Modem Wake Up applications.
For Internal Modem Card (AOpen F34/MP32):
1. Go into BIOS setup , Power Management
Modem Wake Up, select
Enable.
2. Setup your application, put into Windows 95 StartUp or use Suspend to
Hard Drive function.
3. Turn system power off by soft power switch.
4. Connect 4-pin Modem Ring-On cable from F34/MP32 RING connector to
AX5T/AX58 connector WKUP.
5. Connect telephone line to F34/MP32. You are now ready to use Modem
Ring-On.
For External Box Modem:
1. Go into BIOS setup , Power Management
Modem Wake Up, select
Enable.
2. Setup your application, put into Windows 95 StartUp or use Suspend to
Hard Drive function.
3. Turn system power off by soft power switch.
4. Connect RS232 cable of external box Modem to COM1 or COM2.
4. Connect telephone line to external box Modem. Turn on Modem power
(you must keep Modem power always on). You are now ready to use
