IV. BIOS
(BIOS Features)
PCI/VGA Palette Snoop (Disabled)
Some display cards that are nonstandard VGA, such as graphic accelerators or MPEG
video cards may not show colors properly. Setting this to Enabled should correct
this problem. Otherwise, leave this on the default setting of Disabled.
Video ROM BIOS Shadow (Enabled)
This field allows you to change the video BIOS location from ROM to RAM. Relocat-
ing to RAM enhances system performance, as information access is faster than the ROM.
C8000 - CBFFF Shadow to DC000 - DFFFF Shadow (Disabled)
These fields are used for shadowing other expansion card ROMs. If you install other
expansion cards with ROMs on them, you will need to know which addresses the
ROMs use to shadow them specifically. Shadowing a ROM reduces the memory
available between 640KB and 1024KB by the amount used for this purpose.
Boot Up NumLock Status (On)
This field allows users to activate the Number Lock function upon system boot.
Typematic Rate Setting (Disabled)
When enabled, you can set the two typematic controls listed below. Default setting
is Disabled.
Typematic Rate (Chars/Sec) (6)
This field controls the speed at which the system registers repeated keystrokes. Op-
tions range from 6 to 30 characters per second. Setup default setting is 6; other
settings are 8, 10, 12, 15, 20, 24, and 30.
Typematic Delay (Msec) (250)
This field sets the time interval for displaying the first and second characters. Four
delay rate options are available: 250, 500, 750, and 1000.
Security Option (System)
When you specify a Supervisor Password and/or User Password (explained later in
this section), the Security Option field determines when the system prompts for the
password. The default setting is System, where the system prompts for the User
Password every time you start your system. The other option is Setup, where the
system goes through its startup routine unless the Setup utility is called, when the
system prompts for the Supervisor Password.
