   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.
