I installed a new floppy for this rig for my daughter...new round cable as well. On boot up it gives me a "floppy disk failure (40)". I Googled and it says either a faulty cable ( nope..tried another known good cable...still no go), a bad drive ( nope...tried it on my own rig and it's good), or a bad I/O connection.

What is this I/O connection...is it the actual connection on the board where you plug in the cable? But that can't be...see following points.

I have checked Bios...floppy seek enabled ( is first on boot order)

Device Manager shows it to be working properly.
I tried both psu floppy pins...no go.
Floppy cable is oriented correctly also

When I needed to flash the Bios a few weeks ago, I used an older floppy that I had and it worked just fine.

I'm stumped on this one...I have tried everything that I know to check.

I can't remember when this disk error first started...but I remember that I saw this even when I had no floppy drive installed...I just ignored it, thinking that it was thinking that I had a drive installed when I really did not...which was weird, but hey...computers can be really weird at times!!

Hopefully there is some little setting or something that I don't know about.
