One problem is keeping up with PowerPC hardware. It's all different. Most bootroms don't leave enough information, so the kernel is full of code which guess which variety of motherboard it's running on, then behaves accordingly. There's all the different Apple chipsets, all the embedded boards, a different interrupt routing for each prep machine. There just aren't as many types of Alpha, and there isn't a new 68k machine every week. A lot of differences in the five trees are about coping with this. - Adrian Cox, AG Electronics
