Hi guys,
It's been a while since my first post. I got all the parts for my 486 build and squeezed it into an old ATX case, everything was going fine until I came to the floppy drive.
The mobo I am using and am experiencing the problem with is an ASUS 486 SP3:

I have 3 floppy drives, I have tested all of them on an Asus M2V-TVM motherboard and they all work (they will read my MSDOS boot disk).
The floppy cable I am using has both 3 1/2" Floppy Connectors and 5 1/4" Connectors. It works fine on the Asus M2V-TVM. I also have tried numerous other floppy cables.
I am ensuring I plug the marked side of the ribbon cable into PIN 1 and 2 on the motherboard and floppy.
I have set the BIOS to boot from A then C, enabled the onboard floppy disk controller, turned on floppy seek during boot up, the floppy is assigned to IRQ6 and enabled and Swap drive letters is off.
The floppy is connected to an ATX power supply (not AT) - It is the same PSU I tested the Asus M2V-TVM on.
I have tried placing the floppy at various points on the ribbon cable to no avail.
The floppy drive does not light up during boot up even though floppy seek it turned on. The "Floppy disk(s) fail (C0)" message appears and the floppy has done absolutley nothing.
Note - The problem was occuring before I did this but whilst trying to get the thing started I connected the pins going into the floppy the wrong way round which resulted in the floppy light staying lit constantly. I tested the drive in the Asus M2V-TVM and it still works fine.
Is there any way to fix this? Anything I could be missing - I think my motherboards floppy disk controller or pins must be knackered. Pin 1 and 2 on the mobo are very slightly bent outwards compared to the others but when I connect the cable I ensure they slot in.
I don't want to buy an FDC as I want to use the one built into the mobo. Has anyone got any solutions? I feel I am doomed to have to buy another mobo (and this one wasn't cheap!).
