7.2.4 FDD/CD Daughter Board Connector

The ATA backplane provides a pathway for floppy and IDE33 signals from the 100-pin

floppy/FP/IDE connector to the high-density FDD/CDROM daughter board connector. See

Chapter 8 for additional details on the FDD/CDROM interface assembly.

7.2.5 Front Panel Interface Connector

The ATA backplane provides a pathway for front panel signals from the 100-pin floppy/FP/IDE

connector to the front panel (FP) connector. The pinout for the FP (WY*:BHS-33A-2.0D-SM)

connector is shown in the following table.
