4.BIOS CONFIGURATION

Award's BIOS ROM has a built-in Setup program that allows users to modify the
basic system configuration. This type of information is stored in battery-backed
CMOS RAM so that it retains the Setup information when the power is turned
off.

Power ON the computer and press <Del> immediately will allow you to enter
Setup. If the message disappears before you respond and you still wish to enter
Setup, restart the system to try again by turning it OFF then ON or pressing the
"RESET" bottom on the system case. You may also restart by simultaneously
press <Ctrl>, <Alt>, and <Del> keys.

• Primary HDDs / Secondary HDDs

The category identifies the types of hard disk from drive C to F that has
been installed in the computer. There are two types: auto type, and user
definable type. User type is user-definable; Auto type which will
automatically detect HDD type.

Note that the specifications of your drive must match with the drive table.
The hard disk will not work properly if you enter improper information for
this category.

If you select User Type, related information will be asked to enter to the
following items. Enter the information directly from the keyboard and press
<Enter>. Such information should be provided in the documentation form
your hard disk vendor or the system manufacturer.

CYLS. Number of cylinders
HEADS number of heads
PRECOMP write precomp
LANDZONE Landing zone
SECTORS number of sectors

If a hard disk has not been installed select NONE and press <Enter>.

• Drive A type / Drive B type

The category identifies the types of floppy disk drive A or drive B that has
been installed in the computer.

• Video

The category detects the type of adapter used for the primary system
monitor that must match your video display card and monitor. Although
secondary monitors are supported, you do not have to select the type in
setup.

EGA/VGA Enhanced Graphics Adapter/Video Graphics Array. For

EGA, VGA, SVGA, or PGA monitor adapters
CGA 40 Color Graphics Adapter, power up in 40 column mode
CGA 80 Color Graphics Adapter, power up in 80 column mode
MONO Monochrome adapter, includes high resolution

monochrome adapters

• Halt on

The category determines whether the computer will stop if an error is
detected during power up.

NO Errors The system boot will not stop for any error that may

be detected and you will be prompted

All Errors Whenever the BIOS detects a non-fatal error the

system will be stopped

All, But Keyboard The system boot will not stop for a keyboard error;

it will stop for all other errors

All, But Diskette The system boot will not stop for a disk error; it will

stop for all other errors

All, But Disk/Key The system boot will not stop for a keyboard or disk

error; it will stop for all other errors

BIOS Configuration

• Memory

The category is display-only which is determined by POST (Power On Self
Test) of the BIOS.

Base Memory

The POST of the BIOS will determine the amount of base (or
conventional) memory installed in the system.

The value of the base memory is typically 512 K for systems with
512 K memory installed on the motherboard, or 640 K for systems
with 640 K or more memory installed on the motherboard.

Extended Memory

The BIOS determines how much extended memory is present
during the POST.

This is the amount of memory located above 1 MB in the CPU's
memory address map.

Expanded Memory

Expanded Memory in memory defined by the Lotus / Intel /
Microsoft (LIM) standard as EMS.

Many standard DOS applications can not utilize memory above
640 K; the Expanded Memory Specification (EMS) swaps

memory, which not utilized by DOS with a section, or frame, so
these applications, can access all of the system memory.

Memory can be swapped by EMS is usually 64 K within 1 MB or
memory above 1 MB, depends on the chipset design.

Expanded memory device driver is required to use memory as
Expanded Memory.

Other Memory

This refers to the memory located in the 640 K to 1024 K address
space. This is memory that can be used for different applications.

DOS uses this area to load device drivers to keep as much base
memory free for application programs. Most use for this area is
Shadow RAM.
