Driove Not Found error

I recently upgraded my motherboard to gain an AGP socket;
and now Windows 98SE says it can't find the B: drive (it's
a 5.25" FDD) - although when I insert the Startup disk,
the DOS DOES find and access the drive just fine! Any I
deas? Someone suggested a BIOS upgrade, but with
Command.com able to use the drive, that doesn't seem
right - OTOH; if I bring up the DOS prompt FROM WINDOWS,
the drive is no longer accessible..........
All help on this would be appreciated.....
[and yes, the cables are all plugged in ]

If you have Tweak UI installed, make sure B: drive is marked on the My
Computer tab.
