Greetings Earthlings... Ok I ended up putting another 220R in the rack and trying that out. Booted straight away, and has an earlier version of the firmware/openboot.
I think the problem was a busted/faulty scsi controller or something.. because booting either disk0 or cdrom never ever came up with any errors, it always hung. But on the other E220R, it just says 'The file just loaded does not appear to be executable' or some such. So yep. Anyhow, OpenBSD still does not boot up properly on it (stops somewhere after talking about rootdevices or some such ), but thats another story, and I will upgrade the firmware first. Cheers, Josh.
