Dear all,

I've submitted this bug report a week ago:
http://sourceforge.net/tracker/?func=detail&aid=2962575&group_id=180599&atid=893831

I was wondering if work has already been done on this (maybe the problem was already known) and whether patches to fix this and/or workarounds are known.


MINIX is using big real mode which is currently not well supported by kvm on Intel hardware:

(qemu) info registers
EAX=00000010 EBX=00000009 ECX=49200000 EDX=0000a796
ESI=00000200 EDI=49200200 EBP=00000009 ESP=0000a762
EIP=0000f4a7 EFL=00023002 [-------] CPL=3 II=0 A20=1 SMM=0 HLT=0
ES =0000 00000000 0000ffff 0000f300
CS =f000 000f0000 0000ffff 0000f300
SS =9492 00094920 0000ffff 0000f300
DS =97ce 00097cec 0000ffff 0000f300

A ds.base of 0x97cec cannot be translated to a real mode segment.

There is some work to get this to work, but it is proceeding really slowly. It should work on AMD hardware though.
