I just tested this on the iMac with a different HD and installing Debian Lenny Beta2 (since I couldn't find a download for Etch) -- took forever to do but turns out it was worth it -- your patch WORKS! :-) Congratulations.

Thanks very much for hanging in there and fixing this. -- Chris -- Chris Knadle [EMAIL PROTECTED] _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
