Description 
Choice 
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.
