Boot Up Floppy Seek
When enabled, the BIOS will check whether the floppy disk drive installed is 40 or 80
tracks. Note that the BIOS cannot distinguish between 720K, 1.2M, 1.44M and 2.88M
drive types as they are all 80 tracks. When disabled, the 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 360KB.
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 wherein the function of the numeric keypad is the
number keys. When set to Off, the function of the numeric keypad is the arrow keys.
Gate A20 Option
This entry allows you to select how gate A20 is handled. Gate A20 is a device used to
address memory above 1 Mbyte. Initially, gate A20 was handled via the keyboard
controller. Today, while keyboards still provide this support, it is more common, and
much faster, for the system chipset to provide support for gate A20.
Fast The chipset controls Gate A20.
Normal A pin in the keyboard controller controls Gate A20.
Typematic Rate Setting
Disabled Continually holding down a key on your keyboard will cause the BIOS to
report that the key is down.
Enabled The BIOS will not only report that the key is down, but will first wait for a
moment, and, if the key is still down, it will begin to report that the key
has been depressed repeatedly. For example, you would use such a
feature to accelerate cursor movements with the arrow keys. You can
then select the typematic rate and typematic delay in the "Typematic
Rate (Chars/Sec)" and "Typematic Delay (Msec)" fields below.
Typematic Rate (Chars/Sec)
This field allows you to select the rate at which the keys are
accelerated.
Typematic Delay (Msec)
This field allows you to select the delay between when the key was
first depressed and when the acceleration begins.
