In the kernel for PPC, a lot a code is here just to do what doing RTAS : pci config, via (CUDA and PMU) (no need if no ADB keyboard), ... When doing embedded systems, this drivers is very big and can be saving by using RTAS which i think is a very good thing in CHRP specification. It's strange that apple do not provide it fully.Well, they didn't care about it. Note that Macs are far from beeing embedded boxes ;)Yes, but i'm using embedded term for small system that doing dedicate task and only one (for example firewall, gateway, ... in only 50-100k kernel size). I'm actually experienced that with G4 with 4 network card.And what's the smallest amount of memory you can put in a G4? I guess it's an order of magnitude larger than a kernel containing all possible drivers :-)
Sure, but G4 is just a good computer for experimentation !
