Please excuse the many messages...I tried the following at the
openfirmware prompt:
boot /[EMAIL PROTECTED],f2000000/[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL

and got the error
MAC-PARTS: specified partition is not valid
BOOTP/BSPD failed, no FILENAME specified|id
any thoughts?
Wes,
I use "boot sdb1:,\\yaboot" in OF to boot using my second SATA disk.
This brings up the boot prompt from where I choose my kernel.

Hi guys, thanks for the info. Here's what I've done:
--mount sdb3
--edit yaboot.conf
--chroot /mnt/sdb3 (where sdb3 is mounted)
--mount -t proc none /proc
--ybin -v
I also tried
--mount sdb3
--edit yaboot.conf
--chroot /mnt/sdb3 (where sdb3 is mounted)
--mount -t proc none /proc
--exit
--mount /mnt/sdb3 /usr/sbin/ybin
neither of these have solved by booting problem. I am completely
stumped here. Are there config files somewhere that ybin create that
I can look for on sdb3 or sdb2 to see if my yaboot.conf changes are
reflected in the ybin -v output?
thanks,
wes

You're right that I don't need to do the source thing. I do have a
question about "chroot /mnt/ur.sdb3.mnt.pt /usr/sbin/ybin" however.
By doing this command, will ybin now access the modified yaboot.conf
in sdb3? What is it that chroot is doing in this command? I realize
this is a basic question, but I'm kind of fuzzy on what the function
of chroot is.
thanks,

Things get complicated, and "chroot" is a way of simplifying the
situation. Most commands do not run in isolation, i.e. they're not
statically compiled nor run independent of support files. As a
consequence "chroot" allows you to run "that" command in the environment
that it was intended to run. So by doing a chroot on the ybin, you not
only selected the proper yaboot.conf, but also you used a different
ybin, i.e. the one on your installed system and not the one on the
ubuntu livecd. It then used the OF support files on *your* installed
system and everything else that your yaboot.conf is implicitly relying
upon. It's really pretty nifty.
