User's Manual
The "Boot Up Floppy Seek" default setting is "Disabled". When
enabled, the BIOS will check if there is a 360KB floppy disk drive
installed. Don't change the default setting unless your system has a
360KB floppy disk drive.
"Boot Up NumLock Status" is a convenience feature. When the
computer boots, this setting defines which function, the numeric
values, or the cursor controls, will function on the numeric keypad
of IBM-compatible keyboards. The extended keyboards supplied
with most compatible systems have separate cursor control keys. It
is therefore unnecessary to use the numeric keypad to control the cur-
sor. The default setting is "On".
"Boot Up System Speed" sets the CPU speed at boot up. The de-
fault setting is "High".
/DE HOD Block Mode
The "IDE HDD Block Mode" default setting is "Disabled". This
feature enhances hard disk performance by making multi-sector
transfers instead of one sector per transfer. Most IDE drives, except
very early designs, can use this
feature.
Keyboard Interface
The "Typematic Rate Setting" default setting is
"Disabled".
If
enabled, you can set the typematic controls that follow.
The "Typematic Rate (Char/Sec)" controls the speed at which the
system registers repeated keystrokes. The choices range from 6 to 30
characters per second (default is 6).
The "Typematic Delay (Msec)" controls the time between the
display of the first and second characters. There are four delay rate
choices: 250ms, 500ms, 750ms and lOOOms (default is 250ms) .

Password Control
The "Security Option" controls the Password Setting in the main
screen.
The default setting is "System", uses the User Password fea-
ture every time you boot up. The other setting is "Setup". This will
allow the system to boot, and use the Supervisor Password only to
protect the Setup Utility settings from being tampered with. You cre-
ate a password by using the Supervisor or User Password command
from the main screen as explained later in this section.
Shadow Controls
The default setting for "System BIOS Shadow" is
"Enabled".
This will copy the system BIOS into the system DRAM to improve
performance.
The
default setting for the "Video BIOS Shadow" is
"Enabled".
This copies the video display card BIOS into system DRAM to im-
prove performance.
The next ten lines, "C8000-CBFFF Shadow" to "E8000-EBFFF
Shadow" are for shadowing other expansion card ROMs. The default
setting for these areas is "Disabled". If you have other expansion
cards with ROMs on them, you will need to know which addresses
the ROMs use to shadow them specifically. If you don't know and
cannot find out, you can enable all of the ROM shadow settings.
This
ensures that any ROMs present will be
shadowed.
It will also
reduce
the m emory available between 640KB and 1024KB.
After you have made your selections in the BIOS FEATURES
SETUP press the <Esc> key to go back to the main screen.
The
next
item is CHIPSET FEATURES SETUP.
