7.5.4ATA-100 Connector

The Server Board SE7520JR2 provides one legacy ATA-100 40-pin connector (J3K1). The pinout is defined in the following table. Its signals are not tied to the ATA functionality embedded into the high-density 100-pin front panel connector. Each connector is configured to a separate ATA port embedded in the ICH5-R.
