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)
This field determines when the system prompts for the password. The default set-
ting is System, where the system prompts for the User Password every time you boot
up. The other option is Setup, where the system always boots up, and prompts for
the Supervisor Password only when the Setup utility is called up. You can specify a
password by using the Supervisor Password or User Password option from the main
screen as explained later in this section.
PS/2 Mouse Function Control (Auto)
The default of Auto allows the system to detect a PS/2 Mouse on bootup. If de-
tected, IRQ12 will be used for the PS/2 Mouse. IRQ12 will be reserved for expan-
sion cards if a PS/2 Mouse is not detected. Disabled will reserve IRQ12 for expan-
sion cards and therefore the PS/2 Mouse will not function.
PCI/VGA Palette Snoop (Disabled)
This function controls how VGA compatible and graphic devices handle accesses to
VGA palette registers. The active VGA device always responds to a read of color
palette, wihile either the VGA or graphic agent will be programmed to respond to
write transactions to the color palette and the other will be to snoop it. Some display
cards that are nonstandard VGA such as graphics accelerators or MPEG Video Cards
may not show colors properly. The setting Enabled should correct this problem.
Otherwise leave this on the setup default setting of Disabled.
OS/2 Onboard Memory > 64M (Disabled)
When using OS/2 operating systems with installed DRAM of greater than 64MB,
you need to Enable this option otherwise leave this on the setup default of Disabled.

Video BIOS Shadow (Enabled)
This field allows you to change the video BIOS location from ROM to RAM. Relo-
cating to RAM enhances system performance, as information access is faster than
the ROM.
C8000-CBFFF to DC000-DFFFF (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.
