Boot Up System Speed (High)
This allows you to determine the system speed when the system boots up. By
default, the system boots up at high speed.
Gate A20 Option (Normal)
This entry allows you to select how the gate A20 is handled. The gate A20 is a
device used to address memory above 1M bytes. Initially, the gate A20 was
handled via a pin on the keyboard. Today, while keyboards still provide this
support, it is more common, and much faster, for the system chipset to
provide support for gate A20.

Typematic Rate Setting (Disabled)
When disabled, continually holding down a key on the keyboard will generate
only one keystroke. On the contrary, the BIOS will report repeated keystrokes
when this field is enabled. For example, you may use this feature to
accelerate cursor movements with the arrow keys.
