As others have said, dns=1 is correct for your hardware. What does not make any sense is that when
you boot from your floppy reading /D0 works but not when booting from Drivewire.
Now clearly you can read /D0 when booting from /D0. What happens if you boot from /D0 and then try
to read the problem disk in say /D1? More to the point, if you boot from /D0 and then enter
can you read LSN0 on the problem disk?
Cleaning the 3.5" drives can't hurt but that issue is not consistent with the problem you are
reporting. Booting from a floppy would be just as susceptible to dirty heads as booting from Drivewire.
