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.

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

4-7

address space. This is memory that can be used for different

¡ô¡õ¡÷¡ö

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.
