P5XV3 System Board User’s Manual
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 via the keyboard controller. 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
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.
Typematic Rate (Chars/Sec)
This selection allows you to select the rate at which the keys are
accelerated.
Typematic Delay (Msec)
This selection allows you to select the delay between when the key
was first depressed and when the acceleration begins.
