This appendix describes the system board connector pin assignments.

The following “System Board Connectors” table lists the connectors and sockets on the system board. The table also cross-references the page numbers where the connectors and their pinouts are described. The figures show the locations of the connectors and sockets on the system board.

The tables following the figures list each connector by its function, number, and type.

B-8 Connector Pin Assignments

IDE Interface Connector

All signal levels in the IDE interface are TTL compatible. A logic 1 is a signal whose voltage level is between 2.0 and 5.0 V. A logic 0 is a signal measuring between 0.00 and 0.70 V.

The two system board IDE connectors are physically identical. The following table provides the IDE pin assignments. All signals on the Host interface have the prefix HOST. All negatively active signals are further prefixed with a “-” designation. All positively active signals are prefixed with a “+” designation.
