I'm assuming and hoping this is not a repack sealed box...

First does your cable have two ends on it? One with a little joystick icon, and one with a floppy disk?

If you have the right cable that's a good start. IF you have something else that say has and audio plug on it, or multiple other connections they could have slipped you a PC Dos card cable, or something which is not going to work.

I don't remember if you have to set the drive up in the iie card slot assignment or not. You might want to check that you also have Slot 6 mapped to a floppy drive in the software too.

Knocking the rust off the brain with this one for sure.

Good luck! I hope you have the correct cable however!
