  Yes. There exists an autoboot program named SIMMFIX.
The ONLY thing it does is check if the computer THINKS it has 4 MB
and the MMU says it has 2.5MB. Then, it sets the MEMTOP correctly,
and reboots.
    ^^^^^^^
    - several descriptions are around of what happens then.
      Some get bombs, some don't, my computer didn't do anything,
      that is, the memtop wasn't corrected at all. I rewrote the
      program: it jumped to the hd_init vector (or something sounding
      alike) in stead of taking the real reset vector, which had the
      effect that my machine (with no Hard Disk) did not reset. I changed
      this, and it worked fine.

If I'm talking nonsense, please state so on the news. If someone's interested,
do the same, by mail. At this moment, my STE is at the manufacturer for the famous
HD-problem (problem #2 :-/ ) for some months already. I have not had the opportunity
to test anything I said here.
