Award BIOS Setup

All personal computer use a BIOS, or Basic Input/Output system, to
porvide control for the hadrware functions. When system is powered
on or reset, the CPU is reset and BIOS will do the following:

Self-test on CPU.
Verify ROM BIOS checksum.
Verify CMOS configuration chip.
Initialize timer.
Initialize DMA controller.
Verify system memory and cache memory.

Install all BIOS function call utilities.
Verify/initialize all system configurations, like keyboard, floppy

drive, hard disk, initialize EGA or VGA if there is any.
Hook to the add-in BIOS (Include NCR

pansion BIOS to perform initialization and driver link to the
tern.

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 RAM so that the setup information is retained

when the power is turned off. When the system is powered on or reset,

the Award BIOS will display a copyright message on the screen, then
the BIOS will perform the system diagnostics test and initialization.

The Award BIOS supports three HDD modes: NORMAL, LBA, and

3.2 BIOS Features Setup Menu

LBA mode: Logical Block Addressing mode is a new HDD accessing
method designed to overcome the

528

Megabytes limitation. The num­ber of cylinders, heads, and sectors shown in setup ‘may not be the
number physically contained in the HDD. During HDD accessing the
IDE controller will transform the logical address described by cylinder,
head, and sector number into its own physical address inside the HDD.
The maximum HDD size supported by the LBA mode is 8.4 Gigabytes.

LARGE mode: Some IDE

HDDs

contain more than 1024 cylinders

without LBA support. This access mode tricks DOS (or other OS) that

the number of cylinders is less than 1024 by dividng it by 2. At the same
time, the number of heads is multipiled by 2. The maximum HDD size
supported by LARGE mode is 1 Gigabyte.

The BIOS Features setup program is equipped with a series of help

screens accessed by the < Fl > key, which will display the available

options for a particular configuration feature and special help for some
of the options. If you don’t really understand the meanings of each item,
please don’t change the following default values.

PM Control by
APM

Choose Yes (Default) or No. APM stands for

Advanced Power Management. “Yes” makes your

power management more flexible.

Video Off Method Choose DPMS, Blank screen, or V/H Sync +

Blank (Default). With this item V/H SYNC is
controlled by software. If you have a VGA card
that is not compatible with the default option,
switch to “Blank screen”, even though it consumes
more power than “V/H SYNC + Blank”. If your
VGA card and VGA monitor support VESA
DPMS, switch the option to “DPMS”.

Video Off Option Choose “Always On” (Default), “All Modes -- off

(Suspend, Standby and Doze mode), “Stby --Off’.

mode, Standby mode or Suspend mode.

HDD Power Down Choose a time interval from 1 to 15 minutes or

“Disabled” (Default). When the set time has
elapsed, the BIOS sends a command to the HDD
to enter idel (sleep) mode, turning off the motor.
This function is only valid for IDE

HDDs

that

support power saving function.

Doze Mode

The default setting is Disabled. When the Power
Management item is switched to “User Define”

you can select a time interval from 10

set

to 1 hour.

When the set time elapses without activity the

system enters Doze mode.

If the idle time for all PM events-

greater than the Doze time you set the system will
enter Doze mode, and the CPU speed slows down.
If the Video Off Option is set to “Doze, Susp -­Off”, the screen shuts off.
