This is only in-development at this stage, so I only have this going in
a virtual environment. I have machines of separate architectures (x86
PC-BIOS and PowerPC OPAL) booting from the same directory of pxe
configuration files:

 /pxelinux.cfg/arch-0000
 /pxelinux.cfg/arch-000e

The arch-0000 file is being used by for the x86 machines running
pxelinux, and arch-000e for the powerpc machines running petitboot.

Cheers,


Jeremy
