yes, RS/6000 machines use x86 partition tables, and thier OF apparently doesn't load a bootblock (lame IMO). so you create a bootstrap partition large enough to hold yaboot (800K is more then enough). and yaboot is dded directly to it. ybin 1.0 and later supports this with the `fstype=raw' configuration option. the partition must be type 0x41 (note i always get that mixed up its 0x4something) PReP Boot. 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/
