–
Mouse Port
enables or disables the computer's integrated Personal
System/2 (PS/2)-compatible mouse port. Disabling the mouse
allows an expansion card to use interrupt request (IRQ)12.This
setting is used to control the use of this legacy device.
–
Serial Port 1 and Serial Port 2
configure the computer's integrated
serial connectors. You can set these options to
Auto
(the default)
to automatically configure a connector, to a particular designation
(
COM1
or
COM3
for
Serial Port 1
;
COM2
or
COM4
for
Serial
Port 2
), or to
Off
to control the use of this legacy device or to
disable the connector.
If you set a serial connector to
Auto
and add an expansion card
containing a connector configured to the same designation, the
computer automatically remaps the integrated port to the next
available connector designation that shares the same IRQ setting
as follows:
COM1
(input/output [I/O] address 3F8h), which shares IRQ4
with
COM3
, is remapped to
COM3
(I/O address 3E8h).
COM2
(I/O address 2F8h), which shares IRQ3 with
COM4
, is
remapped to
COM4
(I/O address 2E8h).
NOTE:
When two COM connectors share an IRQ setting, you can use
either connector as necessary, but you may not be able to use them both at
the same time. If you are running the Microsoft
®
Windows
®
95 or IBM
®
OS/2
®
operating system, you cannot use both serial connectors at the
same time. If the second connector (COM3 or COM4) is also in use, the
integrated connector is turned off.
–

connector. Press <Enter> to configure the

parallel connector. To determine the correct mode to use, see the
documentation that came with the device.
I/O Address
: This option determines the I/O address used by the
parallel connector and appears except when
Mode
is set to
Off
.
You can set
I/O Address
to
378h
(the default),
278h
, or
3BCh
.
NOTE:
You cannot set the parallel connector to
3BCh
if
Mode
is set to
EPP
.
