Module Connectors

There are three connectors on the module (J8 is not used). Since none is keyed, look for a
pin 1 designation on both the cable connector and the module connector.
The speaker connector (J5 SPKR) works correctly, even if the connector is put on upside
down. Speaker connector pinouts are listed in Table G-2 below:

Use the CD connector to route CD audio from a CD-ROM drive to the audio card. The
CD connector (J6 CD) left and right channels are reversed if you put the connector on
upside down. Pinouts for the CD connector are listed in Table G-3:
