Boot Other Device
The BIOS attempts to load the operating system from the
devices in the sequence selected in these items.
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.
