Sure, I burned it to a CDROM and booted from that per SRM. The screen went black for a second, then the SRM console came back with: ?05 HLT INSTR PC=00000000.20000014 PSL= 00000000.00000007 I wonder if we would be able to see more on a serial line - I can try that perhaps tomorrow or at the weekend. To find out to what code the PC is pointing to, I would need to understand to what point in memory SRM loads the image into.... But this way, the process of loading the kernel definitely worked - I still don't understand why aboot can load the old kernel but not the new one. I'll have a look at the aboot sources, perhaps there's a certain limit on kernel size? I'm not sure if we can call this progress, CU, Uli -- Dipl. Inf.
