|I removed the floppy drive controller in Device Manager and rebooted. Win98 found new hardware and reinstalled the floppy controller. Now both A and B show up correctly. Thanks all for your help! :)|
Key learning for anyone wanting to install a 5.25" floppy drive in addition to existing 3.5" drive:
Must have BIOS support for second drive, with the selectable option for a 5.25" drive
OS is not an issue. All windows version will support a second floppy drive.
You will need a 5 connector universal 34 wire cable with a 7-wire twist. 3 connector is fine if the connectors match your drives.
Jumper the 5.25 as DS1 (same as the other drive!). It's the twist in the cable that does the differentiation.
Use a DOS bootdisk to check out your 5.25" drive first, then get windows to see the second drive using Device Manager per top of this message.
