Gate A20 Option
Gate A20 refers to the way the system addresses memory
above 1MB (extended memory). When set to Fast
(default), 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.
Typematic Rate Setting
This selection enables or disables the Type Rate and
Typematic Delay options that control the speed at which
a keystroke is repeated.
Typematic Rate/Typematic Delay
Typematic Rate selects the typematic rate at which
characters repeat when a key is held down. The default
setting is 6 (Chars/Sec). Typematic Delay controls the
gap between key compression and appearance of the
characters on the screen. The default setting is 250
(Msec).
Security Option
This selection determines whether the password will be
asked for in every system boot or only when entering into
the Setup (default) program.
PCI/VGA Palette Snoop
Alters the VGA palette setting while graphic signals pass
through the feature connector of the VGA card and are
processed by the MPEG card. Enable this option only if
you have MPEG connections through the VGA feature
connector; this means you can adjust PCI/VGA palettes.
The default setting is Disabled.
