[OpenBIOS] CHRP booting.

[Jd Lyons]

I’m trying to figure how Openbios boots CHRP boot scrips like :tbxi, yet SOLF does not.

Can anyone point me to the code in Openbios that enables :tbxi/CHRP booting?

Also, does anyone know how exactly that works, what was done to Openbios to enable booting the Mac OS?

I’d really like to try and get Apple’s BootX to load on Qemu’s pseries machines and as I understand it CHRP booting should work in SLOF, but it just errors out on BootX with "bad executable”, so there must be some magic I need to understand about :tbxi CHRP boot scripts that SLOF needs some sort of patch.
