CHAPTER 8 - BIOS Setup
84
SPI-8450-LLVA
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.
