Hardware Installation

The system board is equipped with an onboard serial port (COM

1). It is also equipped with a 9-pin connector (COM 2) for connect-

ing an external serial port. The serial ports are RS-232 asynchronous

communication ports with 16C550A-compatible UARTs that can be

used with modems, serial printers, remote display terminals, and

other serial devices.

To connect an external serial port, please refer to the following de-

scription. The serial port may be mounted on a card-edge bracket.

Install the card-edge bracket to an available slot at the rear of the

system chassis then insert the cable connector to COM 2. Make

sure the colored stripe on the ribbon cable is aligned with pin 1 of

COM 2.

BIOS Setting

Configure the serial ports in the Integrated Peripherals submenu

(“Super IO Device” section) of the BIOS. Refer to chapter 3 for
