Chapter 3 BIOS Setup

BIOS Setup is an overview of the BIOS Setup Program. The 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.

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 manual type. Manual 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

&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. (Default value)

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.

&&

&&

& 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.

40 tracks 720 K, 1.2 M and 1.44 M are all 80 tracks.

Enabled BIOS searches for floppy disk drive to determine it is 40 or 80 tracks. Note

that BIOS can not tell from 720 K, 1.2 M or 1.44 M drive type as they are
