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 determine if it is 40 or
80 tracks. Note that BIOS cannot 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.
Boot Up NumLock Status:
This allows you to determine the default state of the numeric
keypad. By default, the system boots up with NumLock on.
On Keypad is number keys
Off Keypad is arrow keys
Gate A20 Option:
This entry allows you to select how the gate A20 is handled. The
gate A20 is a device used to address memory above 1 Mbytes.
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 system chipset to provide
support for gate A20.

Typematic Rate Setting:
This determines if the typematic rate is to be used. When
disabled, continually holding down a key on your keyboard will
generate only one instance. In other words, the BIOS will only
report that the key is down. When the typematic rate is enabled,
the BIOS will report as before, but it will then wait a moment, and,
if the key is still down, it will begin the report that the key has been
depressed repeatedly. For example, you would use such a feature
to accelerate cursor movements with the arrow keys.
Enabled Enable typematic rate
Disabled Disable typematic rate
