Type

This parameter lets you set the IDE device type that your system supports.
The options are User, Auto, CD-ROM, Type 1-46, and Not

Installed. Select Auto to automatically configure the installed hard

disk or IDE device. Select CD-ROM if you have a CD-ROM installed in your
system. If you have an old type HDD installed, you may need to enter the
HDD parameters manually. To do this, you must set this parameter to User.
Select Not Installed to bypass the function.

LBA/Large Mode

This enhanced IDE feature allows the system to use a hard disk with a
capacity of more than 528 MB. This is made possible through the Logical
Block Address (LBA) mode translation. Set the parameter to Off to disregard

the feature.

This parameter becomes non-configurable when the HDD Type parameter is
set to Auto.

Block Mode

This function enhances disk performance depending on the hard disk in use.
If enabled, it allows data transfers in block (multiple sectors) by increasing the
data transfer rate to 256 bytes/cycle. However, if your hard disk does not
support this function, set this parameter to Off.

This parameter becomes non-configurable when the HDD Type parameter is
set to Auto.

3-5

32-bit Mode

Enabling this parameter improves system performance by increasing the hard
disk access to 32-bit mode. However, make sure that your hard disk supports
this function before you enable the parameter. Otherwise, set this parameter
to Off.

PIO Mode

Setting this parameter to On allows the system to use a faster hard disk drive.
If your hard disk does not support the PIO mode feature, set this parameter to

Off.

This parameter becomes non-configurable when the HDD Type parameter is
set to Auto.

HARD DISK TYPES

After you have set all the necessary parameters, press . A list of the
HDD drive parameters appears:

Select your hard disk type. Press or to move among the selections.
After you have made your selection, press .

Enable the parameter if you want to skip some POST routines during the boot
process. Set this to Disabled to let the system perform all the POST

routines and follow the specified boot-up sequence.

Boot-up Sequence

The boot-up sequence allows you to specify the system search sequence.
The selections are C:, A:, CD-ROM , A:, C:, CD-ROM and

CD-ROM, A:, C:. If you have a bootable CD-ROM installed, you may

set the CD-ROM as the first priority. The default is A:, C:, CD-ROM.

Boot-up Numlock

Setting this parameter to On enables the numeric function of the numeric
keypad. Set this parameter to Off to disable the function. Disabling the
numeric function allows you to use the cursor control numeric keypad. The

default setting is Off.

Floppy Drive Swap

This parameter allows you to swap floppy drives. For example, if you have two
floppy drives (A and B), you can assign the first drive as drive B and the
second drive as drive A or vice-versa. Disable the parameter to bypass the
function. The default is Disabled.

Floppy Drive Seek

When enabled, BIOS detects whether there is a floppy disk drive installed in
the system. Disable the parameter to skip the function.

Typematic Rate

This parameter allows you to control the speed at which the system registers
repeated keystrokes.

Always, a password prompt appears every time you turn on the computer

and when you enter Setup. When set to Setup, the password prompt
appears when you try to enter setup. The Optimal and Turbo default setting is

Setup.

OS/2 Compatible Mode

Enable the parameter if your system is utilizing an OS/2 operating system and
has a memory size of more than 64 MB. Otherwise, set this to Disabled.

The default setting is Disabled.
