I have an Asus P5VD2VM mobo. I have a 3,5" floppy drive connected at A:. How do I connect a 5,25" floppy drive at B:? The system BIOS does not seem to contain that option.

also, do we actually need a 5.25 tag? isn't it a bit ambiguous, and localized? – Journeyman Geek Jun 10 '12 at 11:40

Its not very likely you can - A: and B: being reserved are a historical artifact, and I do distinctly recall, granted this was a very long time ago that when you had more than one 5.25 inch floppy drive, each had a separate controller card (this was pre IDE).

What I don't remember is if they used a standard floppy controller of the type you would find on a 'modern' floppy.

In addition your motherboard at most would have a single floppy drive connector (which the manual confirms). As is, you would have nowhere to plug in a second drive - and as such it shouldn't show up in the system bios on a vanilla motherboard without a controller card.

If you had a suitable card to run additional floppy drives, it will very likely take care of the boot related changes needed.

Finally A: and B: is a dos/windows/cpm(maybe) ism. The OS should handle that.

Quite simply, running a dual floppy system without additional hardware to take care of the grotty bits isn't something ASUS thought was likely enough to have an option for in the hard drive.

One floppy cable is for two drives. – kinokijuf Jun 10 '12 at 18:31
