It was thus said that the Great Curt Vendel once stated:

  If it is MFM and you have DEBUG (which if you have MS-DOS, you probably
do), then:

C:\>debug
-g c800:0005

  (and when you get back to the DEBUG prompt "-")

-q

C:\>

If the machine crashes or does something really odd when you type
"g c800:0005" into DEBUG, then you either don't have an MFM drive that can
be low lever formatted, or the MRM ROM has been mapped elsewhere in the
region of $A0000-$EFFFF.
