They use OF. Same 1275 chrp binding as other boards. They'll do a typical bootp/tftp boot.a } What firmware do IBM's use? I thought they had their own implementation } of OF. If so, tftp boot is easy. If you don't find anyone else I can do it. } I sure would love an IBM tester. I don't know if the kernel I've built } has sufficient support for what iss on the IBM iron...but I can add it } real quick if I get feedback.
