I use QEMM-386, Version 5.0. It is very finicky and I have had crashes
that I simply don't understand, like when I exclude the VGA BIOS area
from mapping. Eventually I have worked my way around them.

386Max is in my opinion superior because they can loadhi device drivers
like Sun PC-NFS sockdrv.sys which QEMM-386 can not. I have not done
this but people say it works.

I don't think Above Disk or Turbo EMS use the 386 MMU. As far as I can
tell, Qualitas has the best product.
