8.6.7 Floppy Connector
The SE7501WV2 server board provides two separate interfaces to the floppy drive controller.
The first is a legacy 34-pin connector (J1G1), and the second is embedded in the high-density
100-pin floppy / front panel / IDE connector (J2G1).
Note: Using both connectors in a common system is not supported.
The following tables detail the pin-out of the 34-pin legacy floppy connector.
