The serial ports are asynchronous communication ports with 16C550A-compatible UARTs that
can be used with modems, serial printers, remote display terminals, and other serial devices.
Connecting External Serial Ports
Your 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 serial port cable to the COM
connector. Make sure the colored stripe on the ribbon cable is aligned with pin 1 of the COM
connector.

The DVI-I port is used to connect an LCD monitor. This port supports DVI-D signal only.
Connect the display device's cable connector to the DVI-I port. After you plug the cable con-
nector into the port, gently tighten the cable screws to hold the connector in place.
BIOS Setting
Configure the display device in the Chipset menu ("North Bridge Configuration" submenu) of
the BIOS. Refer to chapter 7 for more information.
