the screen during the POST (Power On Self Test), press <Del> key or simultaneously press <Ctrl>,
<Alt>, and <Esc> keys.
TO ENTER SETUP BEFORE BOOT PRESS : <CTRL-ALT-ESC> OR <DEL> KEY
If the message disappears before you respond, restart the system by turning it OFF then ON or
pressing the "RESET" button on the system case. You may also restart by simultaneously pressing
<Ctrl>, <Alt>, and <Delete> keys. If you do not press the keys at the correct time and the system

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.
There are two ways to boot up the system:
1. When VGA as primary and monochrome as secondary, the selection of the video type is “VGA
Mode”
2. When monochrome as primary and VGA as secondary, the selection of the video type is
“Monochrome Mode”.
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
Error halt
The category determines whether the computer will stop if an error is detected during power up.
No errors Whenever the BIOS detects a non-fatal error the system will be stopped and you
will be prompted.
All errors The system boot will not be stopped for any error that may be detected.
All,But Keyboard The system boot will not stop for a keyboard error; it will stop for all other errors.
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 Self Test) of the BIOS.
symbol 254 \f "MS LineDraw" \s 10.5} 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.
symbol 254 \f "MS LineDraw" \s 10.5} 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.
symbol 254 \f "MS LineDraw" \s 10.5} 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.
symbol 254 \f "MS LineDraw" \s 10.5} Total Memory
System total memory is the sum of basic memory, extended memory, and other memory.

Virus Warning
This category flashes on the screen. During and 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 an anti-virus program to locate the problem.
! WARNING !
Disk boot sector is to be modified
Type "Y" to accept write or "N" to abort write
Award Software, Inc.
Enabled Activates 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.
Disabled No warning message to appear when anything attempts to access the boot sector or
hard disk partition table.
Note: This function is available only for DOS and other OSes that do not trap INT13.

Boot Up Floppy Seek
During POST, BIOS will determine if the floppy disk drive installed is 40 or 80 tracks. 360K type
is 40 tracks while 760K, 1.2M and 1.44M are all 80 tracks.
Enabled BIOS searches for floppy disk drive to detemine if it is 40 or 80 tracks. Note that BIOS can
not tell from 720K, 1.2M or 1.44M drive type as they are all 80 tracks.
Disabled BIOS will not search for the type of floppy disk drive by track number, Note that there will
not be any warning message if the drive installed is 360K.
