Sorry but this answer is VERY wrong. QEMM versions 5.11 and above is
definitely compatible with Windows - the best thing since sliced bread &
I use it all the time, as do many others.

The most likely problem is with your SCSII disk drive. There has been
quite a bit of talk about this on the net but, sorry, I don't have the
problem so I didn't keep the references.

You might solve the problem by getting rid of QEMM but you'll lose an
awful lot of memory in the process. I think this problem is partly
addressed in the frequently asked questions posting for ms windows.

I _think_ the answer is to exclude from QEMMs processing that portion of
upper memory which is used by the SCSII adapter for data transfer. Sorry
I can't be more definite - but don't give up on QEMM
