Punky's Dilema, A1200 won't read floppy drive

[punkyclown]

Hello, I just swapped out the mother board of an A1200 I have, put in 3.1 roms put the Keyboard and floppy drive back on screwed down everything, but when I power it up it won't read the floppy.  First I get a blank screen and just the power light, after about 30 seconds the drive light comes on (I can hear it spinning) but nothing happens and then I get the 3.1 rom screen with the insert floppy anim.  Any Ideas, this drive worked fine on the other mother board, I had it attached to an 1960 monitor which shorted out after that the software
would not load and I got a bunch of write errors, I was told here it was the CIA chips, the drive still fired up and tried to load the software and recognized the floppy.
Thanks

I put my hard drive on it and it recognizes and tried to boot it, I get the first screen of the startup and then a requester window saying no disk in CDO.  Also I have no response from my mouse, though I was able to type loadwb which it carried out but did not close the startup screen.  I think there are multiple problems here....

Okay, I was all wet about the mouse which meant I was all wet about my hard drive, once I got my mouse plugged in correctly I was able to cancel the no disk in CDO and my hard drive booted fine and is running fine.  DF0: reads 'DF0:unreadable' so any help I can get on that would be great.  I did notice that there was one pin missing on the Floppy drive on board connector, I don't think that would do it, do you?  And if it would, how to fix?
Thanks

Okay, I have now hooked up a second drive, is recognized and works fine, and then the CD-Rom drive, same thing, recognized and running fine.  So really my only problem is DF0:.
Thanks.
