OpenFirmware uses this partition as the bootblock on IBM machines. why IBM OF doesn't just try and load the first block on the disk, or the first block on a partition when you do something like boot hd: or boot hd:1 ill never understand... that would eliminate the need for these ugly kludgeboot partitions. -- Ethan Benson http://www.alaska.net/~erbenson/
