Award BIOS Setup
Regardless of which setting is chosen, the operator can still use the
turbo switch to toggle between High and Low modes during operation.
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 by 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
Enable the typematic function if you want to be able to configure
the key-repetition characteristics of your keyboard. When typematic is
disabled, continually holding down a key on your keyboard will
generate only one instance. In other words, the BIOS will only report
that the key is down. When the typematic rate is enabled, the BIOS
will report as before, but it will then wait a moment, and, if the key is
still down, it will begin the report that the key has been depressed
repeatedly. For example, you would use such a feature to accelerate
cursor movements with the arrow keys.
