I’ve had quite a problem getting {Darwin} 8.0.1 to boot on my B&W – holding down the C key doesn’t work, and so that is pretty much it as there are no other instructions… Now I have been messing around with the OpenFirmware settings quite a bit so may have stuffed up some invisible extra, but that’s because I feel comfortable with {Sun}’s OpenBoot (and so have half a clue and am more therefore more dangerous to myself) and like to tell the firmware what I think of it. Regularly.

Having a spare Mac to hand helps here, as coming from a non-Mac background the whole bless thing is alien to me, but running bless -info on the {Darwin} CD was very helpful indeed: you can force the boot to take place from the ok prompt with:

boot cd:,\System\Library\CoreServices\BootX

There. That was obvious, wasn’t it ? Still, given that this is {Darwin} and not {OpenDarwin} things get complex after this point, but that’s the fun of messing around with it.
