Think this is only on models 158 & 159. ATs do not seem to exhibit
this. Have seen it with ZDOS 3.0-3.3 - writes to the C drive boot
record (not the MBR).  Different locations with each OS. Possible that
if you zero the locations in the boot record (just the ones it writes)
it might stop writing but cannot confirm this.
