It is mildly complicated compared to other platforms. As far as I know, the document describing the process isn't available outside of HP but the mklinux guys obviously had access to it. I can get something going here if no one else volunteers. Note that my machine is a C160 (64-bit PA8000 based). I think most of you have 700 series machines. I should be able to get one going that will work in w=0 (32-bit) mode so that it will also work with the 700 machines. But someone with a 700 will need to test it and possibly hack it. > > All of this is going to be terrifically difficult without someone with > prior HPPA experience.

There is tons of information about the PDC, IODC, boot process, and I/O architecture that would be very useful -- and its a lot easier to read about than pick through code. I can give what I know/remember. Regards, Jason Eckhardt.
