Video
Select the type of video adapter present in your system. You can ignore this setting if
you are using a VGA monitor; VGA BIOS will automatically configure this setting.
Halt On
When the system is powered on, BIOS performs a series of diagnostic tests called
POST (Power On Self Test). This function stops the computer if BIOS detects a
hardware error. You can tell BIOS to halt on all errors, no errors, or not to halt on
specific errors.
3-2 Advanced BIOS Features
By choosing the Advanced BIOS Features option from the CMOS Setup Utility menu
(Figure 3-1), the screen below is displayed. This sample screen contains the
manufacturer's default values for the motherboard.
Virus Warning
When you set as enabled, you receive a warning message if a program (specifically, a
virus) attempts to write to the boot sector or the partition table of the hard disk drive.
Many disk diagnostic programs that access the boot sector table can trigger the
virus-warning message. If you plan to run such a program, we recommend that
you first disable the virus warning.
CPU L1 & L2 Cache
Cache memory is much faster than conventional DRAM system memory. These fields
allow you to enable or disable the CPUs Level 1 built-in cache and Level 2 external
cache. Both settings are left enabled to significantly increase the performance of your
computer.
Quick Power On Self Test (POST)
Enable this function to reduce the amount of time required to run the POST (Power On
Self Test). BIOS will save time by skipping some items during POST. It is
recommended that you disable this setting. Discovering a problem during boot up is
better than loosing data during your work.
First/Second/Third/Boot Other Device
This option sets the sequence of drives BIOS attempts to boot from after POST
completes. BIOS will search these drives for an operating system.
Swap Floppy Drive
Enabling this function will swap the floppy drive assignment so that drive A will
function as drive B, and drive B will function as drive A. Note that the boot sequence
assignment mentioned directly above does not include booting from floppy drive B.
This function is useful if floppy drives B and A are of a different format and you want
to boot from floppy drive B.
Boot up Floppy Seek
This is a set up check for floppy power-on after starting the computer system.
Boot Up NumLock Status
This function defines the keyboard's number pad as number keys or arrow keys. If it is
set at on the number keys will be activated, if it is set at off the arrow keys will be
activated.

Gate A20 Option:
This allows you to set the Gate A20 status. When set to [
Fast
], Gate A20 is cont rolled
by chipset. When set to [
Normal
], Gate A20 is cont rolled by a specific pin from the
keyboard controller. Available options are [
Fast
] and [
Normal
].
Keyboard Interface
1. Typematic Rate Setting
When enabled, you can set the following two-typematic control items. When disabled,
the keyboard controller determines keystrokes arbitrarily in your system.
2. Typematic Rate (Chars/Sec)
The typematic rate sets the rate at which characters on the screen repeat when a key is
pressed and held down.
3. Typematic Delay (Msec)
The typematic delay sets how long after you press a key that a character begins
repeating.
Security Option
The Supervisor and/or User Password functions shown in Figure 3-1 must be set to
take advantage of this function. See Section 3.11 for password setting information.
When the Security Option is set to System, a password must be entered to boot the
system or enter the BIOS setup program. When the Security Option is set to Setup, a
password is required to enter the BIOS setup program.
APIC Mode
This item can enable or disable the APIC (
Advanced Programmable Interrupt
Controller
). Due to compliance to PC2001 design guide, the system is able to run in
APIC mode. Enabling APIC mode will expand available IRQs resources for the system.
Available options are [
Enabled
] and [
Disabled
].
MPS Version Control For OS
This item allows you to select which MPS (
Multi-Processor Specification
) version to
be used for the operating system. You need to select the MPS version which is
supported by your operating system. To find out which version to use, consult the
vendor of your operating system. Available options are [
1.4
] and [
1.1
].
OS Select (For DRAM >64MB)
If your system's DRAM is larger than 64MB and you are running OS/2, select OS/2 as
the item value. Otherwise, set the item value to Non-OS/2 for all other operating
systems.
Small Logo(EPA) Show
This setup allows photo that is EPA. Logo.
HDD Instant Recover
This board supports HDD Instant Recover, Select enabled to use the function. Upon
system boot up, the HDD Instant Recover Utility will be shown on the screen. Select
enable or disable to continue booting.
Show POST CODE
Enabling this function can show POST error code on the screen before proceeding to
operating system.
