O.k. I have completed one more step.
I have all the basics except for the normal serial port working
when I flash my code into the ROM.
I have a very minimal palcode built that does a one to one mapping
of virtual and physical address, and it is debugged. For most
pal entry points it simply jumps to a debugging routine.
I can now code virtually everything in C, without weird suprises,
so linuxBIOS on the alpha should go faster now.
I'm guessing I just need to look for an hour or two to find how
to enable the serial port on the ALI M1543 southbridge, and then
anyone with a DS10 should be able to pick the code up and mess around.
Once the serial port is enabled, the next task loading and jumping to
linux. And then tracking down how much of the hardware it can't
handle/detect if I leave it totally unitialized.
So with luck I should be booting linux in another week :)
