The category identifies the types of hard disk from drive C to F that has been installed in the computer.
There are two types: auto type, and manual type. Manual type is user-definable; Auto type which will
automatically detect HDD 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 will be asked to enter to the following items. Enter the
information directly from the keyboard and press <Enter>. Such information should be provided in the
documentation form your hard disk vendor or the system manufacturer.
CYLS. Number of cylinders
HEADS Number of heads
PRECOMP Write precomp
LANDZONE Landing zone

&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
and you will be prompted.
All Errors Whenever the BIOS detects a non-fatal error the system will be stopped.
All, But Keyboard The system boot will not stop for a keyboard error; it will stop for
all other errors. (Default value)

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.
