and grub_, respectively. Because the conversion is trivial and
mechanical, I omit the details here. Please refer to the CVS
if you need more information.
Add support for the newworld apple macintosh (PPC). This has been

generic ieee1275 functions, console and disk support. This should
be easy to port to other architectures with support for Open
Firmware.

the powerpc cpu set the host_vendor to ieee1275. Make sure the i386
