6.3.3
Floppy Drive Connector
The evaluation board provides one 34-pin floppy connector, which is located at J1K1.
6.3.4
Front Panel Connector
The development kit is not shipped with a chassis, so the front panel connector is 
unused by default. However, if you want to place your evaluation board in a chassis, 
refer to 
 for the pinout of the front panel connector J2G1.
