Watchdog Timer Configuration
The WDT is used to generate a variety of output signals after a user
programmable count. The WDT is suitable for use in the prevention of system
lock-up, such as when software becomes trapped in a deadlock. Under these sort
of circumstances, the timer will count to zero and the selected outputs will be
driven. Under normal circumstance, the user will restart the WDT at regular
intervals before the timer counts to zero.

BIOS SETUP
BIOS Introduction
The Award BIOS (Basic Input/Output System) installed in your
computer system’s ROM supports VIA processors. The BIOS provides
critical low-level support for a standard device such as disk drives, serial
ports and parallel ports. It also adds virus and password protection as
well as special support for detailed fine-tuning of the chipset controlling
the entire system.
BIOS Setup
The Award BIOS provides a Setup utility program for specifying the
system configurations and settings. The BIOS ROM of the system stores
the Setup utility. When you turn on the computer, the Award BIOS is
immediately activated. Pressing the <Del> key immediately allows you
to enter the Setup utility. If you are a little bit late pressing the <Del>
key, POST (Power On Self Test) will continue with its test routines, thus
preventing you from invoking the Setup. If you still wish to enter Setup,
restart the system by pressing the ”Reset” button or simultaneously
pressing the <Ctrl>, <Alt> and <Delete> keys. You can also restart by
turning the system Off and back On again. The following message will
appear on the screen:
Press <DEL> to Enter Setup
In general, you press the arrow keys to highlight items, <Enter> to
select, the <PgUp> and <PgDn> keys to change entries, <F1> for help
and <Esc> to quit.
When you enter the Setup utility, the Main Menu screen will appear on
the screen. The Main Menu allows you to select from various setup
functions and exit choices.

Time, Date, Hard Disk Type…
The section below the setup items of the Main Menu displays the control
keys for this menu. At the bottom of the Main Menu just below the
control keys section, there is another section, which displays information
on the currently highlighted item in the list.
Note:
If the system cannot boot after making and saving system
changes with Setup, the Award BIOS supports an override to
the CMOS settings that resets your system to its default.
Warning:
It is strongly recommended that you avoid making any
changes to the chipset defaults. These defaults have been
carefully chosen by both Award and your system
manufacturer to provide the absolute maximum performance
and reliability. Changing the defaults could cause the system
to become unstable and crash in some cases.

BIOS SETUP
Standard CMOS Setup
“Standard CMOS Setup” choice allows you to record some basic
hardware configurations in your computer system 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. You will need to
run the Standard CMOS option, however, if you change your system
hardware configurations, the onboard battery fails, or the configuration
stored in the CMOS memory was lost or damaged.

Hard Disk Booty Priority
This item allows you to arrange the priority of the devices where the
system boots from.
Virus Warning
This item protects the boot sector and partition table of your hard disk
against accidental modifications. If an attempt is made, the BIOS will
halt the system and display a warning message. If this occurs, you can
either allow the operation to continue or run an anti-virus program to
locate and remove the problem.
CPU Internal /External Cache
Cache memory is additional memory that is much faster than
conventional DRAM (system memory). CPUs from 486-type on up
contain internal cache memory, and most, but not all, modern PCs have
additional (external) cache memory. When the CPU requests data, the
system transfers the requested data from the main DRAM into cache
memory, for even faster access by the CPU. These items allow you to
enable (speed up memory access) or disable the cache function. By
default, these items are Enabled.
Phoenix - Award WorkstationBIOS CMOS Setup Utility
Advanced BIOS Features
MB720 User’s Manual 33
Page 38
BIOS SETUP
CPU L2 Cache ECC Checking
When enabled, it allows ECC checking of the CPU L2 cache. Enabling
this feature is recommended because it will detect and correct single-bit
errors in data stored in the L2 cache. It will also detect double-bit errors
but not correct them.
Processor Number Feature
This feature enables the reading of the CPU’s serial number read by
external programs. Enable this if your secure transactions require you to
use such a feature.
Quick Power On Self Test
When enabled, this field speeds up the Power On Self Test (POST) after
the system is turned on. If it is set to Enabled, BIOS will skip some
items.
First/Second/Third Boot Device
These fields determine the drive that the system searches first for an
operating system. The options available include Floppy, LS/ZIP,
HDD-0, SCSI, CDROM, HDD-1, HDD-2, HDD-3, LAN and Disable.
Boot Other Device
These fields allow the system to search for an operating system from
other devices other than the ones selected in the First/Second/Third Boot
Device.
Swap Floppy Drive
This item allows you to determine whether or not to enable Swap Floppy
Drive. When enabled, the BIOS swaps floppy drive assignments so that
Drive A becomes Drive B, and Drive B becomes Drive A. By default,
this field is set to Disabled.
Boot Up Floppy Seek
This feature controls whether the BIOS checks for a floppy drive while
booting up. If it cannot detect one (either due to improper configuration
or its absence), it will flash an error message.
Boot Up NumLock Status
This allows you to activate the NumLock function after you power up
the system.
34 MB720 User’s Manual
Page 39
BIOS SETUP
Typematic Rate Setting
When disabled, continually holding down a key on your keyboard will
generate only one instance. When enabled, you can set the two typematic
controls listed next. By default, this field is set to Disabled.
Typematic Rate (Chars/Sec)
When the typematic rate is enabled, the system registers repeated
keystrokes speeds. Settings are from 6 to 30 characters per second.
Typematic Delay (Msec)
When the typematic rate is enabled, this item allows you to set the time
interval for displaying the first and second characters. By default, this
item is set to 250msec.
Security Option
This field allows you to limit access to the System and Setup. The default
value is Setup. When you select System, the system prompts for the User
Password every time you boot up. When you select Setup, the system
always boots up and prompts for the Supervisor Password only when the
Setup utility is called up.
MPS Version Control for OS
This option is specifies the MPS (Multiprocessor Specification) version
for your operating system. MPS version 1.4 added extended
configuration tables to improve support for multiple PCI bus
configurations and improve future expandability. The default setting is
1.4.
OS Select for DRAM > 64MB
This option allows the system to access greater than 64MB of DRAM
memory when used with OS/2 that depends on certain BIOS calls to
access memory. The default setting is Non-OS/2.
Video BIOS Shadow
This item allows you to change the Video BIOS location from ROM to
RAM. Video Shadow will increase the video speed.
Small Logo (EPA) Show
This field enables the showing of the EPA logo located at the upper right
of the screen during boot up.
