Chapter 2 - The Mainboard

On-Board Peripherals

Your mainboard has all of the standard peripheral interfaces and many

extras built in. This eliminates the need for many peripheral expansion

cards and greatly enhances system reliability.

Integrated on-board peripherals include:

• Two serial ports (16550 UART)

• Parallel port (bi-directional, assigned through SETUP)

• Floppy drive controller (handles floppy drives up to 2.88Mb)

• Two PCI local bus IDE hard drive controller ports, each capable

of controlling two hard drives

Factory installed options:

• SCSI port (supports both SCSI-1 and -2 type devices)

• Ethernet port

• Business audio with speaker output jack, alternate internal

speaker output, and microphone input jack

Serial Ports

Your mainboard has two RS-232C asynchronous serial ports, which are

usually referred to as COM1 or COMA (9-pin) and COM2 or COMB (25-

pin) ports. The serial ports are used to attach mice, serial printers,

modems, or other serial peripheral devices. Both serial ports are 16550

UART compatible for higher data transfer rates.

You can install up to two additional serial ports (COM3 and COM4)

simultaneously in your system. However, because MS-DOS does not

manage more than two COM ports simultaneously very well, you

shouldn’t attempt to use more than two COM ports at the same time.

Specifically, don’t try to use COM1 and COM3 at the same time, or

COM2 and COM4 at the same time.
