3 BIOS Setup

Boot Up NumLock Status

This allows you to determine the default state of the numeric keypad. By default, the system boots up with NumLock on wherein the function of the numeric keypad is the number keys. When set to Off, the function of the numeric keypad is the arrow keys.

Gate A20 Option

This entry allows you to select how gate A20 is handled. Gate A20 is a device used to address memory above 1 Mbyte. Initially, gate A20 was handled via the keyboard controller. Today, while keyboards still provide this support, it is more common, and much faster, for the sys- tem chipset to provide support for gate A20.

Fast The chipset controls Gate A20.

Normal A pin in the keyboard controller controls Gate A20.

Typematic Rate Setting

Disabled Continually holding down a key on your keyboard will cause the BIOS to report that the key is down.

Enabled The BIOS will not only report that the key is down, but will first wait for a moment, and, if the key is still down, it will begin to report that the key has been depressed repeatedly. For example, you would use such a feature to accelerate cursor movements with the ar- row keys. You can then select the typematic rate and typematic delay in the “Typematic Rate (Chars/Sec)” and “Typematic Delay (Msec)” fields below.

Typematic Rate (Chars/Sec)

This field allows you to select the rate at which the keys are acceler- ated.

Typematic Delay (Msec)

This field allows you to select the delay between when the key was first depressed and when the acceleration begins.
