An old 5 1/4 floppy drive and a new current pentium 4 computer Can they work together with win XPpro? If so How. Bios does not show the 5 1/4 drive choice.

As you said, the BIOS won't support it. I doubt that it can be done.

If your BIOS will support it, you might still be able to use the 5.25" drive (by unplugging the 3.5" drive and using a power/cable adapter). Otherwise, unless you're lucky enough to round up an older Backpack LPT floppy drive (or create your own...), it might be easier just to network an older machine with a 5.25" drive to your XP-based machine and copy the data across the network (I'm assuming that you're only trying to salvage what resides on some old 5.25" floppies). Only other thing would be to try to find a PCI-floppy controller (since you don't have any other type of slots) with it's own BIOS that'll handle a 5.25" FDD (don't know if such even exists)...

This post (somewhat haphazardly) also describes a method, though I'm a little doubtful that it'd work or be worth it...:
