Package: qemu Version: 0.9.0-1 --- Please enter the report below this line. --- Following the track from that thread in the forum, I've done some tests and the problem is in the file /usr/share/qemu/bios.bin which is a softlink to the file /usr/share/bochs/BIOS-bochs-latest.
The thing is that the bios.bin provided from qemu is now patched with the bios.diff located in the repository http://cvs.savannah.nongnu.org/viewcvs/qemu/pc-bios/?root=qemu as bios.diff. This patch applies to the bios from bochs. I attach the patch for convenience. but take into account that patch applies to bochsbios, _not_ to qemu itself. As a fast workaround you could overwrite the /usr/share/qemu/bios.bin file provided by qemu with the bios.bin file in the qemu repo http://cvs.savannah.nongnu.org/viewcvs/qemu/pc-bios/?root=qemu I don't really know if this bug applies to qemu or bochs but the thing is that you won't be able to run an already working image of win2K (other versions untested) with qemu 0.9.0.
