0xe9 was originally a BOCHS debug port, and was chosen because it isn't typically used in an IBM compatible PC. The only reference I can find which shows it as an option is "PC radio by CoZet Info Systems". I'd write it up with Xen's meaning, and leave the patch there. I doubt any HVM-capable system has an ISA radio card in it. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
