Gate A20 Option
This entry allows you to select how the gate A20 is handled. The gate A20 is
a device used to address memory above 1 Mbytes. 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 pro-
vide support for gate A20.

Typematic Rate Setting
This determines if the typematic rate is to be used. When disabled, continu-
ally 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 de-
pressed repeatedly. For example, you would use such a feature to accelerate
cursor movements with the arrow keys.
