Gate A20 Option Gate A20 refers to the way the system addresses
memory above 1 MB (extended memory). When set
to
Fast , the system chipset controls Gate A20. When
set to Normal , a pin in the keyboard controller con-
trols Gate A20. Setting Gate A20 to Fast improves
system speed, particularly with OS/2 and Windows.
Typematic Rate Setting When Disabled , the following two items (Typematic
Rate and Typematic Delay) are irrelevant. Keystroke
repeat at a rate determined by the keyboard control-
ler in your system.
When

typematic delay.

/ Sec)
Range between 6 and 30 characters per second. This
option controls the speed of repeating keystrokes.
