7.5.4 ATA-100 Connector
The Server Board SE7520JR2 provides one legacy ATA-100 40-pin connector (J3K1). The pin-
out 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.
