That would be a qemu bug ;) But I don't think so.

That doesn't look too bad. DVD was found and el Torrito recognised.
However, besides the menu thing that hardly anyone uses, there's 3 and a half 
different ways to boot el Torrito: Floppy emulation, hard disk emulation 
and "No Emulation", the latter with some BIOSes loading the whole file 
specified, and others only the first 2k block.

No emulation, one 2k block is what windoze install CDs use, and hence that is 
all that krufty legacy BIOS vendors test. Looks like OpenBIOS doesn't support 
that yet.
