I don't know if this DR-DOS 7 EMM386 problem is caused by
the CPU or the mainboard, although the latter is the more likely.
It wasn't a problem previously with DR-DOS 6 EMM386 (or with
MonoSoft EMM386, although this requires HIMEM, which was
the work-around I found with DR-DOS 7 EMM386).
Incidentally, I don't have a spare Intel Pentium I CPU to try,
nor all the mainboard jumper details, so I can't test whether
the problem is caused by the 6x86L CPU or the mainboard.
The only compatibility problem I've had with this CPU was
with a previous version of Xine, which was trying to use MMX
instructions, which this CPU doesn't have. That was a bug
in the software, it might have done the same on a non-MMX
Intel Pentium I.
