Both the SCSI and ATA-100 versions of the SE7501WV2 server board provide legacy ATA
support. There are two separate interface connectors for ATA. The first is a low-density 40-pin
connector which supports ATA-100, and the second is embedded in the high-density 100-pin
floppy / front panel / IDE connector and supports ATA-100.
The following table provides the pin-out for the 40-pin legacy connector.
