Hmm, okay... I'm thinking it's possible that the floppy connector might be off by a pin or two to one side. I wasn't really working in that great a light when I installed the floppy. Here's hoping...
Is a motherboard having a bad FD connector a common problem? I'm hoping that's not the problem... Mounting that thing was a pain in my arse!!
Thanks again though. I'll try what you suggested and if it still doesn't work, I'll be back here again.
