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 key-
boards still provide this support, it is more common, and much faster, for
the system chipset to provide support for gate A20. The default value is
Fast.

Typematic Rate Setting
When disabled, continually holding down a key on your keyboard will
cause the BIOS to report that the key is down. When the typematic rate
is 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 arrow keys.
Enabled Enable the typematic rate.
Disabled Disable the typematic rate.
