[Qemu-devel] FreeDOS FDAPM kills Keybord |

Hello
I have tried to debug the nasty problem, that I loose the keyboard
input in QEMU, when using FreeDOS with HIMEM, EMM386 and FDAPM. I
found a "raise_exception 0xd" in the debug log. I think this is a GPF.
If I use HIMEM and FDAPM, it works fine.
Because HIMEM, EMM386 and FDAPM is working on a real machine, could
there be an error in QEMU ? The interesting point is around the "hlt"
command.
Andreas
