Unless the B&W doesn't support CMD-OPT-O-F, that should always work. Perhaps
you held it down too late or not long enough (you did press the letter 'O',
and not the number, right?)

This is clearly your problem. If you partitioned the third drive properly,
mac OS should not even see it under any circumstances, unless you created a
proper HFS partition, which doesn't appear to be the case, or the Mac OS
wouldn't have a problem mounting it. Additionally, the fact that open
firmware doesn't even know it is there shows that there is something wrong
with the drive or its installation. It has nothing to do with Linux--and
yaboot/ybin only knows what OF tells it.

And it works on PPC with YDL 2.1, a least for everyone else. Have you
searched the archives for people who have had similar issues? If you don't
find anything, it's a good sign that you did something wrong.

Have you tried reformatting the drive as HFS only, and see if OF sees it as
/dev/hdd? If so, follow the YDL installation instructions carefully making
sure that the partitioning is correct. Remember that you must partition
first with HD setup per instructions, and then have the installer finish the
partitioning. If not, you have a bigger problem than installing Linux.
