Boot Up Floppy Seek
When Enabled, the BIOS tests (seeks) floppy drives to
determine whether they have 40 or 80 tracks. Only
360-KB floppy drives have 40 tracks; drives with 720
KB, 1.2 MB, and 1.44 MB capacity all have 80 tracks.
Because very few modern PCs have 40-track floppy
drives, we recommend that you set this field to
Disabled to save time.
Seeks disk drives during boot up. Disabling speeds
boot up.
Boot Up NumLock Status
Toggle between On or Off to control the state of the
NumLock key when the system boots. When toggled
On, the numeric keypad generates numbers instead of
controlling cursor operations.
Gate A20 option
Gate A20 refers to the way the system addresses
memory above 1 MB (extended memory). When set
to Fast, the system chipset controls Gate A20. When
set to Normal, a pin in the keyboard controller
controls Gate A20. Setting Gate A20 to Fast improves
system speed, particularly with OS/2 and Windows
Typematic Rate Setting
When Disabled, the following two items (Typematic
Rate and Typematic Delay) are irrelevant.
Keystrokes repeat at a rate determined by the
keyboard controller in your system. When Enabled,
you can select a typematic rate and typematic delay.
Typematic Rate (Chars/Sec)
When the typematic rate setting is enabled, you can
select a typematic rate (the rate at which character
repeats when you hold down a key) of 6, 8, 10,12, 15,
20, 24 or 30 characters per second.
