Just wanted to give an update. On Sunday, Uwe was able to run some
tests with "legacybios". What was found:
* coreboot-v2 can run legacybios. It does require disabling
valid_area() check in in src/boot/elfboot.c
* legacybios will start up on real hardware (tested with coreboot-v2),
but there were some issues with kbd init, ide init, and usleep.
This prevented booting a real OS. Latest "legacybios" git should
address kbd init and usleep.
* A more detailed analysis of filo shows that it has a more advanced
ide init (it does a pci scan for ide controllers and it has
"floating bus detection"). I'm going to work on advancing the
"legacybios" code to also do this.
Uwe also put together a wiki page at:
