ports can connect to serial devices, such as a mouse or a printer, or to a
communications network.
The IRQ and address ranges for both ports are fixed. However, if you
want to disable the port or change these parameters later, you can do this
in the system BIOS setup.
Different devices implement the RS-232 standard in different ways. If
you are having problems with a serial device, be sure to check the pin
assignments for the connector.
2.7 PS/2 Keyboard and Mouse Conn (CN11)
Two 6-pin mini-DIN connectors (CN11) on the motherboard provide con-
nection to a PS/2 keyboard and a PS/2 mouse, respectively.
2.8 External Keyboard Connector (CN12)
In addition to the PS/2 mouse/keyboard connector on the AIMB-744's
rear plate, there is also an extra onboard external keyboard connector.
This gives system integrators greater flexibility in designing their sys-
tems.
