- I have the same problem with my 386-40mhz. The problem is caused by shadow
- RAM. certain chip sets put 384k of reserved memory ( I don't know what that
- is, but it isn't the memory between 640k and 1meg ) in low memory with an I/O
- port-selectable method of getting to it. got this info from QEMM. have to
- use the NOSH (no shadow ram) option. don't worry too much, there ain't much
- that can be done.
