You can do some soldering on the drive itself. this works for most pc floppy drives:
1- Set the unit as DS0, instead of DS1 (pc floppy drive standard)-many have jumpers for this.
2- Route the 34 pin trace to pin 2 and cut it from 34 (do this at the 34pin floppy connector)
3- Join pins 30 & 34.
There is a nice thread on the subject on EAB:
