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 provide support for gate
A20.

This determines if the typematic rate is to be used. When 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.
Enabled Enable typematic rate
Disabled Disable typematic rate
When the typematic rate is enabled, this selection allows you select the rate at which
the keys are accelerated.
