CMOS Setup Utility Controls
Two sections of the CMOS Setup Utility allow you to configure how some of your system’s features work. These are:
• BIOS Features Setup
• Power Management Setup
The CMOS Setup Utility is a program that is permanently
stored in the BIOS chip on the mainboard. The utility creates a
system hardware configuration record that it stores in a small
amount of battery-supported memory on the board. The BIOS
uses this record to function as an interface between the system
hardware and the operating system. Most of the settings in the
CMOS Setup Utility are made automatically, so you won’t normally need to use this program. You can, however, customize
some of the operational features to suit how you prefer to use
the program.
The screen illustrations on the next two pages show the Setup
Default settings for these two sections of the utility.

Firmware & Software
The mainboard hardware is supported by both firmware and
software components. Firmware is software that is stored on a
chip on the board rather than on disk media.
The firmware component you interface with on this mainboard is the CMOS Setup Utility. This utility establishes various
settings used by the BIOS, the basic software that is an interface
between the system hardware and software.
The software component is comprised of software drivers that
support the PCI IDE controller and the 5598 model onboard VGA
video display card.
How To Use The CMOS Setup Utility
The CMOS Setup Utility options are listed in detail in Section
4: Reference Information. This section is just a brief explanation
of how to run the program to adjust settings as noted in this and
the next section.
To run the CMOS Setup Utility, press the Del or Delete key
while the computer is starting up, before the operating starts to
load. The utility’s main screen will appear as shown on the next
page. To navigate the program, use the controls shown on the
screen. The utility has several sections. Many of the features configured by the utility are set to operate automatically when the
‘Setup Defaults’, the recommended mode, are used. With Setup
Defaults loaded you can still customize various settings.
Clearing CMOS
Under some unusual circumstances the configuration record
created by the CMOS Setup utility and stored on the mainboard
can become corrupted and unusable, possibly leading to the board
being unable to operate properly. If this happens, the CMOS
record can be cleared by setting jumper JP13 to the clear setting
for a moment and then setting it back to the Normal setting. Refer to Section 4 for more information.

Installing Expansion Cards
Adding System Memory
Installing A CPU Upgrade
Adding An IDE Peripheral
Adjusting Display Memory
Reconfiguring Your Mainboard
This section explains how to install new hardware on your
mainboard. It covers installing expansion cards, adding system
memory , changing the CPU and installing additional IDE peripheral devices such as a hard disk or a CD-ROM drive.
Installing Expansion Cards
There are seven expansion card slots on the mainboard, three
ISA slots and four PCI slots. When you get an expansion card, it
will come with instructions on how to install it, so this section
covers relevant information from the mainboard side only.
ISA Cards & Slots
ISA expansion cards often use system resources in the form of
IRQs and DMA channels. Newer cards that comply with the Plug
and Play (PnP) standard are designed to allow the Operating System to automatically configure system resources. Cards that do
not support PnP may require manual configuration of both the
card hardware and settings in the CMOS Setup Utility.
If you have a PnP-compliant card to install there should be
little to do other than follow the installation instructions. If, however , you have a non-PnP card and it requires configuring system
resources, you may need to review the third part of this section,
Configuring Expansion Card Resources In CMOS Setup.

capability. For installed PCI cards to use this feature an Operating System-specific Bus Master software driver that comes with
this mainboard must be installed under your Operating System.
These drivers are located on the Support Disk. There is more
information about them later in this section.

see Section 4: Reference Information.
Configuring Expansion Card Resources In CMOS Setup
The CMOS Setup Utility , which is covered in detail in Section
4: Reference Information, has a section called PNP/PCI Configuration. The default settings in this section allow the Operating
System to automatically configure IRQ resources for PnP compliant ISA and PCI Cards.
If you need to install a non-PnP card, you will need to configure any IRQ and DMA settings manually, both on the card and
in the CMOS Setup Utility . The following three pages show how
to do this.

This is the default screen for
this section when Setup Defaults are loaded. If you need
to manually configure the IRQ
settings, set the first item on
the screen to the ‘Manual’

CMOS Setup Utility –
Pnp/PCI Configuration
When ‘Resources Controlled
By’ is set to ‘Manual’ you can
individually configure the IRQ
& DMA channel settings. The
individual defaults are for PnP
cards and will still use all the
items listed to automatically
assign resources as needed.
If you are installing a ‘legacy’
ISA card that requires manual
configuration, you can manually assign the required resources as needed. See the
next page for an example.
Page 27
P5ST–A User’s Manual
3: Reconfiguring Your Mainboard – 3.5
CMOS Setup Utility –
Pnp/PCI Configuration
This screen shows an example of a manually configured IRQ setting for a “Legacy’
ISA expansion card. Legacy
cards, by definition, are not
PnP compliant and must be
manually configured if they
require an IRQ or DMA channel. See the card manual for
specifics.
When an item in the list is configured this way , it is no longer
part of the pool of automatically configurable resources.
For this reason, don’t configure ISA cards this way unless
they are Legacy cards.

You can not use SIMM and
DIMM modules at the same
time on this mainboard.
D
Don’t mix DRAM types in the
same SIMM bank, the system
will treat higher performance
EDO DRAM as Fast Page and
any performance benefit will
be lost. You should install
memory of the same speed
in both banks.
Adding System Memory
There are some requirements you must follow if you want to
install system memory. The memory subsystem has four 72-pin
SIMM sockets divided into two banks, SIMM1 & SIMM2 and
SIMM3 & SIMM4. It also has two DIMM sockets. You cannot
use SIMMs and DIMMs at the same time on this mainboard.
SIMM modules should use either Fast Page Mode (FPM) or
EDO 5-V olt DRAM. You can use modules from 4MB to 128MB,
either single or double-sided. DIMM modules must use 3.3-V olt
EDO or SDRAM.. Total supported memory capacity is 256MB.
If your mainboard is already installed in a system, it will have
some amount of memory installed on the board. You can tell
how much by checking the configuration screen that appears
when the computer is starting up. With some memory installed,
there may be sockets available to add additional memory. If not,
you must remove modules to install an upgrade.
Memory Configurations
SIMMs install in pairs. You can install any SIMM memory
combination as long as you follow the basic requirement of installing identical modules in both sockets of a bank, i.e.:
• 5-Volt modules
• Both modules are the same size, e.g. 16MB (MegaBytes)
• Both are the same DRAM memory type, e.g. EDO
• Both use the same operating speed, e.g. 60ns (nanoseconds)
Each DIMM is a memory Bank. You can install DIMMs with
these specifications:
• 8MB to 128 MB single or double-sided module
• 3.3-Volt module
• EDO or SDRAM DRAM
Other than these requirements, there is no limitation on the
variety of possible combinations, so they are not listed here.

You can not use SIMM and
DIMM modules at the same
time on this mainboard.
System Memory Specifications
The memory subsystem has four 72-pin SIMM sockets divided into two banks, SIMM1 & SIMM2 and SIMM3 & SIMM4.
It also has two DIMM sockets and each one is a bank. You cannot use SIMMs and DIMMs at the same time on this mainboard.
SIMM modules should use either Fast Page Mode (FPM) or
EDO 5-V olt DRAM. You can use modules from 4MB to 128MB,
either single or double-sided. DIMM modules must use unbuffered 3.3-Volt EDO DRAM or SDRAM.. T otal supported memory
capacity is 256MB.
Memory Configurations
SIMMs install in pairs. You can install any SIMM memory
combination as long as you follow the basic requirement of installing identical modules in both sockets of a bank, i.e.:
• 5-Volt modules
• Both modules are the same size, e.g. 16MB (MegaBytes)
• Both are the same DRAM memory type, e.g. EDO
• Both use the same operating speed, e.g. 60ns (nanoseconds)
Each DIMM is a memory Bank. You can install DIMMs with
these specifications:
• 8MB to 128 MB single or double-sided module
•Unbuffered 3.3-Volt module
• EDO DRAM or SDRAM
Other than these requirements, there is no limitation on the
variety of possible combinations, so they are not listed here.
Note: It is possible to install more memory than the board
supports. Do not install more than 256MB on this mainboard,
the system will ignore additional memory.

CMOS Setup Utility Summary
This section explains the entries in the CMOS Setup Utility
program. This utility is permanently stored on the BIOS chip on
the mainboard. It creates a record of the mainboard’s and some
system configuration information and stores it in battery-supported memory on the mainboard. This record must be intact
and accurate in order for the mainboard to operate.
After a brief explanation of how to operate the utility there is
a summary of the entries and options for all sections of the utility. Under normal conditions, once your system is set up, you
should have little or no need to use this utility.
Using the CMOS Setup Utility
This mainboard uses the Award system BIOS. It is stored in a
Flash ROM memory chip on the mainboard. The BIOS uses a
software program, also stored on the same chip to create a system configuration record which is saved in a small amount of
special “CMOS” memory on the mainboard.
Accessing The CMOS Setup Utility
When you turn on your computer, a message appears on the
screen indicating you can run the Setup program by pressing the
Del key (it’ s on the keypad.) The message appears after the POST
(Power On Self Test).
If you want to run Setup but you don’t respond in time before
the message disappears, you can reset the system by pressing the
Ctrl + Alt + Delete keys at the same time, or by pushing the
system Reset button. The message will then reappear.
After you press the Del or Delete key the program menu screen
will appear , displaying the Setup utility section names and some
command instructions.

Large Hard Disk Modes
The last of the drive parameter entries – Mode – has four options, Normal, LBA, Large and Auto. The Mode settings are for
IDE hard disks only.
Normal
For IDE hard disks of 528MB or less.
LBA
This stands for Logical Block Addressing, the current standard
access mode for large IDE hard disk drives. It allows the use of
hard disks larger than 528MB by causing the IDE controller to
translate between the logical address it creates and the hard
disk’s actual physical address. The maximum drive size sup-
ported is 8.4GB.
Large
For 1GB or smaller drives with more than 1024 cylinders and
no LBA support. This access mode causes the Operating Sys-
tem to treat the drive as if it has fewer than 1024 cylinders by
dividing the cylinder total in half and doubling the number of
heads. Drives needing this mode are less common.
Most large IDE hard disk drives currently available use the
LBA mode. Use the AUTO setting to automatically detect the
correct mode for new drives.
Floppy Disk Drives
The two floppy disk drive items set the drive type for drives A
and B, and must be entered manually. The options are
360KB, 5.25 in.

What Power Management Does
Power management lets you set up your computer to save
electricity when it is not actively in use by putting the system
into progressively greater power saving modes. In the power management scheme there are four system states which proceed in
the following sequence:
Normal
Doze
Standby
Suspend
Power Management
This controls the entire power management scheme. There
are four settings:
User Defined
You set the power saving options manually
Disable
Turns off all power management
Max Saving
Maximizes power saving by activating maximum power sav-
ing settings after one minute of system inactivity
Min Saving
Produces less power saving by activating moderate power sav-
ing settings after one hour of system inactivity
PM Control By APM
When this is set to Yes the Advanced Power Management feature in Microsoft Windows controls power management operation. The default setting is No.

This governs monitor power saving by controlling how power
management blanks the monitor screen. The default setting blanks
the screen and turns off vertical and horizontal scanning and requires a monitor with “green” features. If you don’t have this
type of monitor, use the Blank option. DPMS (Display Power
Management System) allows the BIOS to control the video display card if the card has the DPMS feature.
V/H SYNC+Blank (Default)
Blank (Non-green monitor, less saving)
DPMS (Display card must support DPMS)
Video Off Option
This governs in what modes the video display gets turned off.
The options are:
Susp,Stby-> Off (Off in Suspend & Standby)
Susp-> Off (Off in Suspend)
All Modes Off (Off in Doze, Suspend & Standby)
Always On (No video shut off)
