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.
