Hi people,
I had to face the same problem witht the same machine and finally came
out with a solution aftre a long struggle. This is not a new question ,
it has been answered already. Maybe you guys at YDL could update the
html pages on the site so that same questions don't come back endlessly.
Here is the content of a mail I sent a few month ago after mailing
to Ethan Benson the guy who wrote Ybin, thanks to him I could get Yaboot
to work. It comes from a problem with yabin that dose not always
recognizes the correct boot-device so you have to put it by hand, Here
is the recipe:
-------------------------------------------------------------------
Hi people,
Finally I got ybin to work on my B/W G3, I got some help from Ethan
Benson (author of yaboot) and of course from all the people here
in the mail-list that helped me to track that problem down.
Here is how I could solve this:
1) Re-initialize the PRAM (holding Alt+Apple+p+r upon reboot).
My PRAM had a few variables not correctly set (I messed them
playing too much in the OF probably...).
2) Choose (Re-choose) my startup disk with the startup-disk
control panel in MacOS. This is very important as it revives
the correct boot-device in the OF.
3) Go back in the OF and read what your boot-device actually is
thanks to step 2. At this point you might check if everything
is OK by simply typing 'boot' in the OF (not mac-boot), if all
is fine it should boot MacOS. Otherwise go back to 1) and 2).
4) Now in the OF simply change the end of the boot device variable
from :\\"tbxi to ofboot.b or yaboot
5) Go back into linux using the CD and run MacOnLinux, you should
see you bootstrap partition mounted on the Mac desktop. You can
then edit and change your ofboot.b and change the boot-device
parameters as required.
6) Reboot and enjoy yaboot...
I have to precise that I have a second non-bootable ADAPTEC SCSI
card for external drives. After discussion with Ethan Benson it
might be possible that ofpath (a routine in ybin) does not see
the internal SCSI card correctly because of this additional external
card. The other possibility is that my P-RAM and boot-device were
set completely wrong in the OF and ofpath got miss-guided because
of this. I have some home-work to do by Ethan to check that out
and I will keep you informed with all hardware information too
(boot-device, additional card...I don't have it with me today).
ThanX to all that gave me a helping hand!!!

And don't listen to people who say your PRAM is dead...
Bye
