Drive C type/Drive D type

The categories identify the types of hard disk drive C or drive D that have been installed in the
computer. There are 46 predefined types and a user definable type. Type 1 to Type 46 are
predefined. Type User is user-definable.

Press PgUp or PgDn to select a numbered hard disk type or type the number and press <Enter>.
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 your hard disk drive type is
not matched or listed, you can use Type User to define your own drive type manually.

If you select Type “User”, related information is asked to be entered to the following items. Enter
the information directly from the keyboard and press <Enter>. This information should be provided
in the documentation from your hard disk vendor or the system manufacturer.

There are the option of Type “AUTO” and Mode “AUTO” to auto detect the hard disk type and the
hard disk mode (Normal, LBA and Large).

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

Note: Mode Setting For Hard Disk Larger than 528MB

The Mode settings are for IDE hard disks only. You can ignore this item for MFM and ESDI
drivers. There are three entries you can select from in the mode field, ”Normal”, ”Large” and
“LBA”.

Set Mode to the Normal settings for IDE hard disk drives smaller than 528MB. Use the LBA
setting for drives over 528MB that use Logical Block Addressing mode to allow larger IDE hard
disks. The Large setting is for drives over 528MB that do not use the LBA mode. This type of drive
can only be used with MS-DOS and is uncommon. The majority of IDE drives over 528MB use the
LBA mode.

Drive A type/Drive B type

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

Video

The category selects 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.

Error halt

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

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 512K for systems with 512K memory
installed on the motherboard, or 640K for systems with 640K 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 1MB in the CPU's memory address map.

Expanded Memory

Expanded Memory is memory defined by the Lotus/Intel/Microsoft (LIM) standard as EMS. Many
standard DOS applications cannot utilize memory above 640K, the Expanded Memory
Specification (EMS) swaps memory which is 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 64K
within 1MB or memory above 1MB, depending on the chipset design.

Other Memory

This refers to the memory located in the 640K to 1024K 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.

Power Management

“Power Management” is the master control for the power saving features, including HDD power down,
Doze, Standby and suspend Modes and the I/O Device Timer, that together form the hard-ware power
conservation scheme. There are three options:
User Defined - Allows you to configure the power conservation features yourself.
Disable - Turn off all the power conservation features.

PM Control by APM

This feature is automatically set to “ON”, the system BIOS will wait for APM prompt before it enters the
GREEN mode.

NOTE : If APM is installed, & if there is a task running, event the timer is time out, the APM will not prompt the

BIOS to put the system into any power saving mode!

Power Management 4DPS

VGA Off Method

There are two options you can choose for which mode to turn off the VGA display.
Blank Screen - The system will blank the screen only.
V/H SYNC + Blank - Choose this mode if your system using the monitor with power

management feature. In addition of the blank screen, the system will turn
off the horizontal and vertical sync signal. Most monitor will turn off
itself if these signal is inactive.

HDD Off Timer

“HDD Off Timer” specifies the period to cause an IDE hard disk to “spin down” if it is not accessed. The
disk returns to full speed the next time it is accessed. Settings range from “10 Min” to “15 Min”, and
“Disabled”.

Green ModeTimer

“Green Mode Timer” specifies the period to cause the system enter power management mode. The
available Settings range is from “20 Min” to “40 Min”, and “Disabled”.

PCI Configuration 4DPS

PCI Configuration

The System BIOS on a PCI platform plays the role of a System Resources Manager. Its main job is to
dynamically allocate system resources such as I/O, Memory & IRQs to all PCI devices without any
conflicts!

Slot 1-3 Using INT#

There are two options in this category
AUTO : BIOS will - ask the PCI device which INT(A-D) does it want to use for interrupt

- check which IRQ is available from the above

- tell the device which IRQ has been assigned to it.
A,B,C,D : These options are reserved for "Dirty" cards from which the system BIOS cannot tell which
INT does it use.
Note : Choose "AUTO" for all devices unless you know exactly which card a dirty device & which INTs

does that card use!
Choose ONLY "AUTO" for Multi-Function PCI devices because options A, B, C, D will force the
BIOS to assign IRQs for function 0 only!

1st-3rd Available IRQ

The System BIOS will assign these 3 available IRQs to the found PCI devices. You can change the IRQ
assignment manually.

PCI IDE 2nd Channel

Enable this option to select the secondary on board IDE controller as your IDE hard disk controller
interface.

PCI IDE IRQ Map to

The system will map the PCI IDE IRQ automatically by PCI-AUTO. You can map to PCI-slot 1-3, ISA,
and the INT# A,B,C,D by yourself.

Exit Setup 4DPS

Load BIOS Defaults

This features stays in the default system values before the user has changed any CMOS values. If CMOS
setting lost. the BIOS defaults will automatically be loaded.

Load Setup Defaults

This features uses to load the default setting for normal use.

Password Setting

When you select this function, the following message will appear on the screen to assist you in creating a
password.

ENTER PASSWORD:

Type the password, up to eight characters, and press <Enter>. The password typed now will clear any
previously entered password from CMOS memory. You will be asked to confirm the password. Type the
password again and press <Enter>. You may also press <Esc> to abort the selection and not to enter a
password.

To disable password, just press <Enter> when you are prompted to enter password. A message will
confirm the password being disabled. Once the password is disabled, the system will boot and you can
enter Setup freely.

PASSWORD DISABLED.

If you select System at Security Option of BIOS Features Setup Menu, you will be prompted for the
password every time the system is rebooted or any time you try to enter Setup. If you select Setup at
Security Option of BIOS Features Setup Menu, you will be prompted only when you try to enter Setup.

IDE HDD Auto Detection

You can use this utility to detect the IDE hard disk parameters and enter it automatically. It can
automatically detect up to four hard disk which connected to the system.

Save And Exit Setup

Select this option when you finished setup the CMOS and it will reboot the system after you press “YES”.

Exit Without Saving

If you decided not to save any change you had made. You can select this option to exit the CMOS setup
and all the change you made will lose. When you select this option and press “yes”, the system will reboot
and the CMOS data will not change.
