Hi,

my experience with the latest QEMU and MS-V is identical to Michael's,
so I think replacing pc-bios/bios.bin in CVS by a newer version of
Bochs which supports ACPI 2.0 (I took the latest stable version)
might help other users, too.

Is pc-bios/bios.diff still needed? Maybe it can be removed in CVS.

Stefan
