If you have a Digital Equipment Corporation (DEC) or Dell system and
you use the BIOS option to logically swap drives A and B, Microsoft
Backup and Microsoft Backup for Windows cannot back up or restore
files to those drives.
This problem occurs because Microsoft Backup reads from the floppy
disk drive through BIOS disk services but writes to the floppy disk
drive directly through the I/O ports.
Microsoft Backup can work successfully with logically swapped floppy
disk drives that are implemented by physically exchanging the hardware
You may be able to work around this situation by using MS-DOS Path as
your backup destination.
