BIOS CONFIGURATION

4. BIOS CONFIGURATION

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 batterybacked CMOS SRAM so that it retains the Setup information when the power is turned off.

4.1. ENTERING SETUP

Power ON the computer and press <Del> immediately will allow you to enter Setup. If the message disappears before you respond and you still wish to enter Setup, restart the system to try again by turning it OFF then ON or pressing the "RESET" bottom on the system case. You may also restart by simultaneously press <Ctrl>, <Alt>, and <Del> keys.

4.2. CONTROL KEYS

The times format in <hour> <minute> <second>. The time is calculated base on the 24-hour military-time clock. For example, 1 p.m. is 13:00:00.

• Primary HDDs / Secondary HDDs

The category identifies the types of hard disk drive C drives F 4 devices that has been installed in the computer. There are two types: auto type, and user definable type. User type is user-definable; Auto type which will automatically detect HDD's 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 is asked to be entered to the following items. Enter the information directly from the keyboard and press <Enter>. Those information should be provided in the documentation form your hard disk vendor or the system manufacturer.

Disabled Normal Floppy Drive. Drive A Drive A is 3 mode Floppy Drive. Drive B Drive B is 3 mode Floppy Drive. Both Drive A & B are 3 mode Floppy Drives.

• Video

The category detects 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.

EGA/VGA Enhanced Graphics Adapter/Video Graphics Array. For

EGA, VGA, SVGA, or PGA monitor adapters CGA 40 Color Graphics Adapter, power up in 40 column mode CGA 80 Color Graphics Adapter, power up in 80 column mode MONO Monochrome adapter, includes high resolution

monochrome adapters

• 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

All Errors Whenever the BIOS detects a non-fatal error the

system will be stopped and you will be prompted

All, But Keyboard The system boot will not stop for a keyboard

All, But Diskette The system boot will not stop for a disk error; it

will stop for all 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.

Expanded Memory

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

Expanded memory device driver is required to use memory as Expanded Memory.

Other Memory

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

• Virus Warning

This category flashes on the screen during after the system boots up, any attempt to write to the boot sector or partition table of the hard disk drive will halt the system and the following error message will appear, in the mean time, you can run anti-virus program to locate the problem. Default value is Disabled.

Enabled Activate automatically when the system boots up causing

a warning message to appear when anything attempts to access the boot sector or hard disk partition table
