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 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 th e <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.

MB770 User’s Manual

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.

CPU L1/L2 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.

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.

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.

BIOS SETUP

MB770 User’s Manual 37

Boot Up NumLock Status

This allows you to activate the NumLock function after you power up
the system.

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.

Security Option

This field allows you to limit access to the System and Setup. When you
select System, the system prompts for the User Password every tim e you
boot up. When you select Setup, the system always boots up and prompts
for the Supervisor Password only when 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 expandab ility. 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 locat ed at the upper right
of the screen during boot up.
