This is a place holder page for the ISA Floppy Disk and Serial Controller
Troubleshooting
The floppy drive works but the C drive is not detected.
This can happen if you have both the XT-IDE and floppy ROM Extensions installed on the same system where the XT-IDE is at a lower address. You will notice that the usual XT-IDE boot screen will not show. In this case make sure the floppy controller address is lower than the XT-IDE.
For example the floppy controller is at 0xCA0000 (higher) and the IDE controller is at 0xC8000(lower) then swap the addresses by adjusting the DIP switches.
