In the BIOS, they need to do two things.
Turn on both floppies, and set the sizes.
I think you said they did that.

If so, check all your cables.
Make sure PIN #1 is connected to the RED
stripe on the cable on the floppies and the MB.

Still no dice?
Boot into safe mode and go to Control Panel,
Device Manager, System, Floppy Drives, and
delete ALL the listed floppy drives.
(There will likely be a few...)

Then re-boot and Windows will find and fix the actual
floppy drives in the machine, (or so the theory goes..)

Good luck,    Rick Glazier

A friend is building a older system for a customer that wants both 3 ½ and 5 ¼ floppies in the system.  The system will see both
floppies in the BIOS but when the system is booted up (Win 98se) it will only see one of the floppies.
