I had a similar problem on my 7200. It turns out that some hard
drives are just not OF friendly, not that it's the hard drives
fault. It would usually boot at least one out of 5 attempts ~:^)
I gave up and hacked the miBoot based boot floppy to do the job for
me, setting the root device and unsetting the prompt for root
floppy. This is not a very happy solution if you want to use a
custom kernel. But really BootX with MacOS is the most versatile
and reliable way to boot these machines with the brain damaged OF.
Somebody posted a URL a few weeks ago where one can download 7.x.x
of MacOS.
The non-versatile OF of these computers makes it hard to have a
non-MacOS based solution. There's been talk of getting yaboot to
work as a second stage to quik, but really quik is fine. The hard
part is getting the OF to read ANYTHING off the hard disk in a
reliable manner.
