still worse, there are those cases (Linux) where the interpretation of PIRQ is broken (e.g. for Geode). So I've reluctantly come to the conclusion that LinuxBIOS should do this routing. > Once we get that we can figure out how to export that information > via the LinuxBIOS table, the mptable, and pirq table.

I would hate to see mkelfImage get too complicated, as I need to be able to generate these elf Images on systems that have no GNUbin utilities. ron _______________________________________________ Linuxbios mailing list [EMAIL PROTECTED] http://www.clustermatic.org/mailman/listinfo/linuxbios
