That was on a 5400/180 though, the 7200 may be worse.

And where can I read docs for it? its a boot loader designed to be loaded by the hardware MacROM found in oldworld powermacs. there is no (or very little) documentation for it. its really not suited to disk based bootstrap, its designed for CD booting. > Would it be possible to pull a yaboot-like bootup with miboot?

MacOS will also destroy the miboot partition if it mounts the bootstrap partition. -- Ethan Benson http://www.alaska.net/~erbenson/
