BIOS Configuration
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 gener-
ates numbers instead of controlling cursor operations.
Boot Up System Speed
Select High to boot at the default CPU speed; select Low to boot at the
speed of the AT bus. Some add-in peripherals or old software (such as
old games) may require a slow CPU speed. The default setting is High.
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 deter-
mined 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.
Typematic Delay (Msec)
When the typematic rate setting is enabled, you can select a typematic
delay (the delay before key strokes begin to repeat) of 250, 500, 750 or
1000 milliseconds.
Security Option
If you have set a password, select whether the password is required
every time the System boots, or only when you enter Setup.
