BIOS Features
HDD S.M.A.R.T. capability (Disabled)
This allows the enabling or disabling of the S.M.A.R.T. (Self-Monitoring, Analysis
and Reporting Technology) system which utilizes internal hard disk drive monitoring
technology. This feature is normally disabled because system resources used in this
feature may decrease system performance.
PS/2 Mouse Function Control (Auto)
The default of Auto allows the system to detect a PS/2 mouse on bootup. If detected,
IRQ12 will be used for the PS/2 mouse. IRQ12 will be reserved for expansion cards
if a PS/2 mouse is not detected. Enabled will always reserve IRQ12, whether on
bootup a PS/2 mouse is detected or not.
OS/2 Onboard Memory > 64M (Disabled)
When using OS/2 operating systems with installed DRAM of greater than 64MB,
you need to set this option to Enabled otherwise leave this on Disabled.

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.
Video ROM 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 640K and 1024K by the amount used for this purpose.
Boot Up NumLock Status (On)
This field enables users to activate the Number Lock function upon system boot.
Typematic Rate Setting (Disabled)
When enabled, you can set the two typematic controls listed next. Setup default set-
ting 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 Pass-
word 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.
