There is (T)MSCP, the (Tape) Mass Storage Control Protokol. It is a
standard way to interface disks (and Tapes) on DEC Uni- and QBus (DSSI)
systems. If your disk adapter speaks MSCP, it will work regardless of
the actual disk type. The reference to the MFM disks is a reference to
the RQDX[123] adapter, that is a MFM to MSCP adapter...

INIT (via RESTART button)
Then type into the boot prom:
D/P/L 20088004 80000001 <cr>
D/P/W 20001f40 20 <cr>
D/P/W 2000146a 3FFF <cr>
S 200 <CR> (or "S 218 <cr>" if you have GPX graphics)
and you will see the adapter menu setup. Reformat the disks, do a bad
block scan and revector the bad blocks from the errorlog.
