What are you using as a boot command in OF?

You'll want something like boot scsi-int/sd@0,0

(No guarantees... OF is weird and different in differnt versions.)

You'll need to make fsck work... but if you can get the drive to boot,
it'll fsck itself (and, if you're *really* bad off, demand to be fscked
manually, which should work). At the worst, just reformat and start
over. (Not as bad as it sounds... things go more cleanly with
progressive retries. ;^>)

Btw, seeing as you work at Apple, don't suppose you could gank us some
OF docs?
