Hello,

I have been testing some parts of FreeDOS on an original IBM PC/XT
and on a 8086 emulator as well. Many things seem to work, but some
things crash.

Below is a short list of problems I encountered.
Things like himem.exe and CD-ROM drivers do not work for obvious
reasons, so those are not listed here.

8086/XT compatibility issues with FreeDOS 1.0:

mkeyb.exe:      crash due to apack compression of the binary
exe2bin.com:    crash on ENTER instruction
swsubst.exe:    crash on ENTER instruction
l.exe:          crash on PUSH imm
mvalues.exe:    crash on ENTER instruction
doslfn.com:     crash, source is full of hand coded 386 instructions
share.com:      crash on ENTER, a different binary with the same release
date works correctly:

Crashes on ENTER usually happen when the compiler generates 286+ code.
Perhaps these could be easily fixed by recompiling with more
conservative settings.

Bye,
  Joris.
