With
Read Only
selected, nothing can be written to any floppy
drive or tape drive using the computer's integrated floppy/tape
drive controller. (The computer can still read from the drives.)
When
Read Only
is selected,
Auto
is also in effect, meaning that
the computer turns off the integrated floppy drive controller as
necessary.
Selecting
Off
turns off the integrated floppy/tape drive controller;
this setting is used to control the use of this legacy device or for
troubleshooting purposes.
–
USB Emulation
: determines whether the computer's basic
input/output system (BIOS) controls Universal Serial Bus (USB)
keyboards and mice. When
On
is selected (the default), the BIOS
controls USB keyboards and mice until a USB driver is loaded by
the operating system. When
Off
is selected, the BIOS does not
control USB keyboards and mice, although they function during
the boot routine. Set USB Emulation to
Off
if you are using a
PS/2-compatible keyboard and mouse.
NOTE:
For Windows NT
®
,
Off
is the default setting.
–
Primary Video Controller
: determines which video controller to
use when the computer boots. When
Auto
is selected, the
computer uses a video expansion card, if one is installed or the
onboard video controller if a video expansion card is not installed.
When
Onboard
is selected, the computer uses the onboard video
controller even if a video expansion card is installed.
–
Video DAC Snoop
: lets you correct video problems that may
occur when you use certain video expansion cards. The default is
Off
. If you are using a video expansion card and problems such as
incorrect colors or blank windows occur, set
Video DAC Snoop
to
On
.
•
Keyboard NumLock
determines whether your computer boots with
the Num Lock mode activated on 101- or 102-key keyboards (it does
not apply to 84-key keyboards). When Num Lock mode is activated,
the rightmost bank of keys on your keyboard provides the
mathematical and numeric functions shown at the top of each key.
When Num Lock mode is turned off, these keys provide cursor-control
functions shown by the label on the bottom of each key.
