NumLock
This option controls whether the NumLock key on the
keyboard is on or off at boot-up. The choices are “Auto”
(default), “On,” or “Off.”
Peripheral Configuration Submenu
This submenu can be used to configure your system’s ports
or peripheral devices. To enter the submenu, highlight this
field, then press
Enter
. The following options appear:
Serial Port A/Serial Port B
These options let you configure your system’s Serial
Port A or Serial Port B. You can choose “Auto,”
“Enabled,” (default) or “Disabled.” The “Enabled”
setting assigns Serial Port A to 2F8h, IRQ3. Note that if
you set a specific serial port address, it does not appear
in the list of options for the other serial port. Serial Port
B is “Disabled.”
!
CAUTION
An asterisk symbol appearing next to an option
indicates that the selected IRQ is set to conflict with
another device.
NOTE
If you select the Enabled option, you’ll see
additional options that allow you to specify the Base
I/O address and IRQs for the port you're
configuring.
