Hardware Installation
Serial Port
The onboard COM 1 port and the 9-pin connector for COM 2 are
RS-232 asynchronous communication ports with 16C550A-compat-
ible UARTs that can be used with modems, serial printers, remote
display terminals, and other serial devices.
Your additional COM port may come 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 connector that is attached to
the serial port cable to this connector. Make sure the colored stripe
on the ribbon cable is aligned with pin 1 of the connector.
BIOS Setting
Configure the serial ports in the Integrated Peripherals submenu
(“Super IO Device” section) of the BIOS. Refer to chapter 3 for
more information.
