AFAIK OSX does not overwrite yaboot, it just changes the
default boot-device.
Not a big problem with Openfirmware:
* Hold 'Command-Option-o-f' after powering-up the machine
(While you hear the sound..)
* You should get a prompt
* type 'boot hd:X,yaboot' , replace 'X' with your boot partition, eg:
0> boot hd:2,yaboot
(If you don't remember/know your boot partition, just try some numbers.
You can't damage anything)
.. this should load yaboot :-)
See:
http://penguinppc.org/bootloaders/yaboot/doc/yaboot-howto.shtml/ch9.en.shtml#s9.2
After the system bootet, try to re-run 'ybin' to change the default
boot-device,
OR do it while you are inside the OpenFirmware prompt.
# setenv boot-device hd:X,yaboot
# nvstore (.. correct?)
# reset-all
> /dev/nvram: No such file or directory"
> Warning: nvram will not be updated"
Hmm... strange..
Maybe a strace output would help
# strace ybin 2>&1 | grep nvram
.. or
# ls -l /dev/nvram
