Table A-3 summarizes the general features of the compute module.

Note: The following table assumes that the expansion compute module does not include an optional IO9 PCI card, which would add one input and one output real-time interrupt port, an Ethernet port, and an internal and external SCSI drive, and support for one serial port. The IO9 card is also needed to support the DVD–ROM, the SCSI disc drives, and the serial daughtercard with the PS/2 connectors and three serial ports (this serial daughtercard is not an option for the expansion compute module).
