CPU INTERNAL CACHE:
EXTERNAL CACHE:
These two categories speed up memory access. However, it depends on
CPU/chipset design.
CPU L2 CACHE ECC CHECKING:
This item allows you to enable / disable CPU L2 Cache ECC checking.
QUICK POWER ON SELF TEST:
This item allows you to speed up Power On Self Test (POST) after power-
up the computer. When enabled, BIOS will shorten or skip some check
items during POST.
BOOT SEQUENCE:
This category determines the sequence for which drive to look for first
when system boots up. You may set the system to look first at drive A:
and then at drive C: or vice versa.
SWAP FLOOPY DRIVE:
This item is effective only in systems wherein there are two floppy drives.
Selecting Enabled assigns physical swapping of drive B to logical drive A
and physical drive A to logical drive B.
BOOT UP FLOPPY SEEK:
You may enable / disable this item to define whether the system will look
for a floppy disk drive to boot at power-on, or directly to the hard disk
drive.
BOOT UP NUMLOCK STATUS:
This item allows you to determine the default state of the numeric keypad.
By default, the system boots up with NumLock on.
GATE 20A OPTION:
This entry allows you to select how the gate A20 is handled. The gate A20
is a device used to address memory above 1Mbytes. Initially the gate A20
was handled via a pin on the keyboard. Today, while keyboards still
provide this support, it is more common and much faster for the sytem
chipset to provide support for gate A20.
