Gate A20 Option; Typematic Rate Setting - Multitech CommPlete RAS96 User Manual

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 MB. Initially, the gate A20 was handled via a pin on
the keyboard. Today, though keyboards still provide this support, it is more common,
and much faster, for the system chipset to provide support for gate A20.

Memory Parity Check
Parity is a method of checking for errors in system memory. There are both parity and
non-parity memory types. At boot, the Award BIOS both sizes and tests all memory.
Normally, when a parity error is detected, the BIOS will display a message describing
the problem as well as the problem's location, if possible. The boot process will then
terminate and you will not be able to continue until the bad SIMM is located and
replaced.
Disabling the Memory Parity Check allows the system to bypass the test and allow
your system to boot. You then have a choice of continuing to operate your system or
attempting to remedy the problem.

Typematic Rate Setting

This determines if the typematic rate is to be used. When it is disabled, continually
holding down a key on your keyboard will generate only one character. 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 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.
