yeah that is not correct, only Newworlds have nice aliases like that (and only for ATA) the 7200 uses scsi/@sd:2:0 i am not entire sure what the 8550 is, like i said, try ofpath it may already support that machine. otherwise you have to look around /proc/device-tree/aliases/ and whatnot. > it was: > boot-device /AAPL,ROM > earlier > > Now on powering up the system I get nothing on the screen, no grey screen, > and it doesn't boot from floppy or Mac CD either.
