That last part is what's confusing me. QEMU should be adding a standard IDE cdrom. That type of cdrom has been around for a long time. You might want to try with just qemu (instead of kvm). Also, if you still can't figure it out, you could try posting your command line and the debug log produced by the commands I sent above. The folks on the qemu list may be able to help as well. -Kevin _______________________________________________ SeaBIOS mailing list SeaBIOS@seabios.org http://www.seabios.org/mailman/listinfo/seabios
