Main Setup Menu
The most commonly accessed and modified BIOS settings are in the
Main
setup menu. The
Main
setup menu includes the following settings:
•
System Time & Date
—This setting controls the time of day, which is
stored in a battery-backed real-time clock. Most operating systems
also include a way to change this setting. Use <+> and <–> in
conjunction with <Enter> and <Tab> to change these values.
•
Require Keyboard to Boot
—When
Enabled
, a missing or
malfunctioning keyboard causes the BIOS to halt with an error. When
Disabled
, the BIOS allows booting without a keyboard. If you are
using a USB keyboard, you may attach it at any time during the
powered up state. To use this controller in a “headless” mode, you must
set this option to
Disabled
. The default value is
Enabled
.
Note
Attaching a USB-to-PS/2 keyboard adapter may allow the system to boot even if no
PS/2 keyboard is attached.
•
Num Lock
—This setting indicates whether you turn on Num Lock at
boot time. The default value is
On
.
•
SATA Port
—This item displays the SATA devices detected in the
system. Normally, you do not need to modify this item. However, if a
SATA device is not autodetected properly, you can specify it manually
by pressing <Enter> on the item.
