I succesfully compiled and tested it with kvm-66 on Ubuntu 7.10, guest Ubuntu 8.04. For the next rounds, could you actually rebase against upstream QEMU and submit to qemu-devel? One of Paul Brook's objections to extboot had historically been that it wasn't not easily sharable with other architectures. With a C version, it seems more reasonable now to do that. Moreover add a binary version of the ROM in the pc-bios directory: it avoids to have a cross-compiler to build ROM on non-x86 architecture. Regards, Laurent Make sure you remove all the old linux boot code too within QEMU along with the -hda checks.
