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 controls Gate
A20. Setting Gate A20 to Fast improves system speed, particularly with
OS/2 and Windows.
