Mouse
enables or disables the systems built-in Personal System/2 (PS/2)-compatible
mouse port. Disabling the mouse allows an expansion card to use IRQ12.

Serial Port 1 and Serial Port 2 configure the systems built-in serial ports. These
options can be set to Auto (the default) to automatically configure a port, to a particu-
lar designation (COM1 or COM3 for Serial
Port
1; COM2 or COM4 for Serial Port 2),
or to Off
to disable the port.
If you set a serial port to Auto and add an expansion card containing a port configured
to the same designation, the system automatically remaps the built-in port to the next
available port designation that shares the same interrupt request (IRQ) setting as
follows:
COM1 (input/output [I/O] address 3F8h), which shares IRQ4 with COM3, is
remapped to COM3 (I/O address 3E8h).
Likewise, COM2 (I/O address 2F8h), which shares IRQ3 with COM4, is
remapped to COM4 (I/O address 2E8h).
NOTE: When two COM ports share an IRQ setting, you can use either port as neces-
sary,
but you may not be able to use them both at the same time
. If the second
port (COM3 or COM4) is also in use, the built-in port is turned off.

Parallel Port configures the systems built-in parallel port. Parallel Port can be set to
378h
(the default), to alternate addresses 278h
or
3BCh,
or to Off to disable the port.
NOTE: Do not set
Parallel Port
to
278h
if you have an Extended Capabilities Port
(ECP) device connected to the port.
