3. AWARD BIOS SETUP
3.1 BIOS Setup
The motherboard supports 5V programmable Flash ROM chips. These memory chips can be
updated when BIOS upgrades are released. Use the Flash Memory Writer utility to download the
new BIOS file into the ROM chip as described in detail in this section.
All computer motherboards provide a Setup utility program for specifying the system
configuration and settings. If your motherboard came in a computer system, the proper
configuration entries may have already been made, If so, invoke the Setup utility, as described
later, and take note of the configuration settings for future reference; in particular, the hard disk
specifications.
If you are installing the motherboard, reconfiguring your system or you receive a Run Setup
message, you will need to enter new setup information. This section describes how to configure
your system using this utility.
The BIOS ROM of the system stores the Setup utility. When you turn on the computer, the
system provides you with the opportunity to run this program. This appears during the Power-On
Self Test (POST). Press the <Delete> Key to call up the Setup utility. If you are a little bit late
pressing the mentioned key(s), POST will continue with its test routines, thus preventing you
from calling up Setup. If you still need to call Setup, reset the system by simultaneously pressing
the <Ctrl>,<Alt> and <Delete> keys, or by pushing the Reset button on the system case. You
can also restart by turning the system off and then back on again. But do so only if the first two
methods fail.
When you invoke Setup, the CMOS SETUP UTILITY main program screen will appear with the
following options:

Load Defaults
The “Load BIOS Defaults” option loads the minimized settings for troubleshooting. “Load Setup
Defaults”, on the other hand, is for loading optimized defaults for regular use, Choosing defaults
at this level, will modify all applicable settings.
A section at the bottom of the above screen displays the control keys for this screen. Take note
of these keys and their respective uses. Another section just below the control keys section
displays information on the currently highlighted item in the list.

AWORD BIOS SETUPAWORD BIOS SETUP
3.2 Standard CMOS Setup
This “Standard CMOS Setup” option allows you to record some basic system hardware
configuration and set the system clock and error handling. If the motherboard is already installed
in a working system, you will not need to select this option anymore. However, if the configuration
stored in the CMOS memory on the board gets lost or damaged, or if you change your system
hardware configuration, you will need to re-specify the configuration values. The configuration
values usually get lost or corrupted when the power of the onboard CMOS battery weakens.
The above screen provides you with a list of options. At the bottom of this screen are the control
keys for use on this screen. Take note of these keys and their respective uses.
User-configurable fields appear in a different color. If you need information on the selected field,
press the <F1> key. The help menu will then appear to provide you with the information you
need. The memory display at the lower right-hand side of the screen is read-only and
automatically adjusts accordingly.

set the current time. Follow the hour, minute and second format. Valid values for hour, minute
and second are:
Hour: 00 to 23
Minute: 00 to 59
Second: 00 to 59
You can bypass the date and time prompts by creating an AUTOEXEC.BAT file. For information
on how to create this file, please refer to the MS-DOS manual.
Hard Disk Drives
This field records the specifications for all non-SCSI hard disk drives installed in your system. The
onboard PCI IDE connectors provide Primary and Secondary channels for connecting up to four
IDE hard disks or other IDE devices. Each channel can support up to two hard disks; the first of
which is the “master” and the second is the “slave”.
Specifications for SCSI hard disks need not be entered here since they operate using device
drivers and are not supported by any of the BIOS. If you install other vendor’s SCSI controller
card, please refer to their respective documentation’s on how to install the required SCSI drivers.
To enter specifications for a hard disk drive, you must select first a “type”. You can select “User”
and specify the specifications yourself manually, or you can select from the provided predefined
drive specifications. To select, simply press the <Page Up> or <Page Down> key to change the
option listed after the drive letter.

Page 12 P6LX-ATX MB Manual
AWARD BIOS SETUPAWARD BIOS SETUP
For IDE hard disk drive setup, you can:
•Use the Auto setting for detection during bootup.
•Use the IDE HDD AUTO DETECTION in the main menu to automatically enter the drive
specifications.
•Enter the specifications yourself manually by using the “User” option.
The entries for specifying the hard disk type include CYLS (number of cylinders), HEAD (number
of read/write heads),PRECOMP (write precompensation), LANDZ (landing zone), SECTOR
(number of sectors) and MODE. The SIZE field automatically adjusts according to the
configuration you specify, The documentation that comes with your hard disk should provide you
with the information regarding the drive specifications.
The MODE entry is for IDE hard disks only, and can be ignored for MFM and ESDI drives. This
entry provides three options: Normal, Large, LBA, or Auto (see below). Set MODE to the Normal
for IDE hard disk drives smaller than 528MB; set it to LBA for drives over 528MB that support
Logical Block Addressing (LBA) to allow larger IDE hard disks; set it to Large for drives over
528MB that do not support LBA. Large type of drive can only be used with MS-DOS and is very
uncommon. Most IDE drives over 528MB support the LBA mode.
Auto detection of hard disks on bootup
For each field: Primary Master, Primary Slave, Secondary Master, and Secondary Slave, you can
select Auto under the TYPE and MODE fields. This will enable auto detection of your IDE drives
during bootup. This will allow you to change your hard drives (with the power off) and then power
on without having to reconfigure your hard drive type. If you use older hard drives which do not
support this feature, then you must configure the hard drive in the standard method as described
above by the “User” option.
NOTE: After the IDE hard disk drive information has been entered into BIOS, new IDE hard disk
drives must be partitioned (such as with FDISK) and then formatted before data can be read
from and write on. Primary IDE hard disk drives must have its partition set to active (also possible
with FDISK).
NOTE: SETUP Defaults are noted in parenthesis next to each function heading.
Drive A/Drive B (None)
These fields record the types of floppy disk installed in your system. The available options for
drives A and B are: 360KB, 5.25in.; 1.2MB, 5.25in,; 720KB, 3.5in,; 1.44MB, 3.5in,;None.
To enter the configuration value for a particular drive, highlight its corresponding field and then
select the drive type using the left-or right-arrow key.

3.3 BIOS Features Setup
This “BIOS Features Setup “ option consists of configuration entries that allow you to improve
your system performance, or let you set up some system features according to your preference.
Some entries here are required by the motherboard’s design to remain in their default settings.
A section at the lower right of the screen displays the control keys you can use. Take note of
these keys and their respective uses. If you need information on a particular entry, highlight it and
then press the <F1> key. A pop-up help menu will appear to provide you with the information you
need. To load the last set values, press the <F5> key. <F6> and <F7> load the BIOS default
values and Setup default values, respectively.
NOTE: SETUP Defaults are noted in parenthesis next to each function heading.
Virus Warning (Disabled)
This field protects the boot sector and partition table of your hard disk against accidental
modifications. Any attempt to write to them will cause the system to halt and display a warning
message. If this occurs, you can either allow the operation to continue or use a bootable virus-
free floppy disk to reboot and investigate your system. This setting is recommended because
conflicts with new operating systems. Installation of new operating systems require that you
disable this to prevent write errors.

MODEM Use IRQ (3)
You can set IRQs 3, 4, 5, 7 individually through modem. Activity detected from any IRQ channel
will wake up the system.
Doze Mode (Disabled)
This item lets you set the period of time after which the system enters into Doze mode. In this
mode, the CPU clock slows down. The ratio is specified in the “Throttle Duty Cycle”. Any activity
detected returns the system to full power. The system activity (or event) is detected by monitoring
the IRQ signals.
Standby Mode (Disabled)
This item lets you set the period of time after which the system enters into Standby mode. In this
mode, CPU clock slows down, hard disk will be shut off and the monitor power-saving feature
activates. Any activity detected returns the system to full power. The system activity (or event) is
detected by monitoring the IRQ signals.
Suspend Mode (Disabled)
This item lets you set the period of time after which the system enters into Suspend mode. The
Suspend mode can be Power On Suspend or Suspend to Hard Drive, selected by “Suspend
Mode Option”.
HDD Power Down (Disabled)
This option lets you specify the IDE HDD idle time before the device enters the power down
state. This item is independent from the power states previously described in this section
(Standby and Suspend).
Throttle Duty Cycle (62.5%)
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 the parameter. Actually, the period per 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.
VGA Active Monitor (Enabled)
To enable or disable the detection of VGA activity for power down state transition.
Soft-Off by PWR-BTTN (Instant-Off)11/28/97
The system can be in one of two states, one is suspend mode and the other is the Soft-Off
mode. Pushing the power button for less than 4 seconds places the system into suspend mode.
When the power button is pressed for more than 4 seconds, it enters the Soft-Off mode.
