Greg Watson almost has it done.
It required a few changes to linuxbios build procedures, but not many. It has small impact.

Here's what I get so far (running from ram). Very close! The malloc error is because the jump to linuxbiosmain code is missing...

Cool.
I would think the problem would be a missing call to elf_boot, not jump to linuxbiosmain.
Has anyone worked out how to boot a PPC kernel yet? There is not a standard PPC firmware so it should be some easier.
Do we need to talk about an etherboot port to PPC?
Is it time to start considering an ADLO like tool that implements openfirmware?
Ron I don't know if we will have time but I will see if I can ring a demo out of you this afternoon, since I'm going to be down there anyway.

I leave that one to Greg.

That's what Stefan Reinauer has been working on. Also steve james has in fact done a forth boot project that is almost there.

the node is off-site, but maybe Greg can bring it in tomorrow.

It works on Itanium so porting should not be too bad.

Right.

Darn. Maybe I can just hope to meet Greg. I'm pretty certain I won't have time to do more than drive to the airport tomorrow.
