Built-in Ports
The system board is equipped with two serial ports, one SPP
parallel printer port, one FDD connector, two IDE hard disk
shrouded headers, and/or one optional PS/2 mouse connector.
Serial Ports
The built-in serial ports are RS-232C asynchronous commu-
nication ports with 16C550A-compatible UARTs that can be
used with modems, serial printers, remote display terminals,
and other serial devices. They use the following system I/O
addresses: (1) COM 1: 3F8h; (2) COM 2: 2F8h.
Connecting the Serial Ports: J4, J5
Two DB-9P serial port cables are provided with the mother-
board. They are mounted on a card-edge bracket along with
the optional PS/2 mouse cable. The upper serial port cable
should be used for the COM 1 primary serial port; connect it
to Connector J4 on the motherboard. The lower serial port
cable should be used for the COM 2 secondary serial port;
connect it to Connector J5 on the motherboard. Make sure
the colored stripes on the ribbon cables are aligned with pin
1 of Connectors J4 and J5.
