IV. BIOS

(BIOS Features)

Typematic Rate Setting (Disabled)

When enabled, you can set the two typematic controls listed next. Setup default

setting is Disabled.

Typematic Rate (Chars/Sec)

This field controls the speed at which the system registers repeated keystrokes.

Options 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) (250ms)

This field sets the time interval for displaying the first and second characters. Four

delay rate options are available: 250ms, 500ms, 750ms and 1000ms.

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)

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.
