That's not bad. OF_open() on "/pci@80000000/ide@7,1/cd@0,1:0" worked and
ofwboot can read blocks from the CD with the OFW read method.

But the error 22 indicates that no valid filesystem was detected. This can
have several reasons:

1. Your CD does not contain a sane ISO9660 filesystem.
2. OF_read claims to work but just returns trash or doesn't fill the buffer
at all.
3. OF_read reads a different block than requested.

Let's concentrate on point 1 first. Are you sure your CD is ok? Is the
"netbsd" or "netbsd.gz" file in the root directory, parallel to ofwbootdb?

I just tried tried the same with a CD and ofwbootdb on my Pegasos2 and FS[1]
does not return error 22. This is the ISO9660 file system.

So cruxppc avoids possible OFW bugs by booting the kernel directly. It
doesn't use any OF_open or OF_read calls.

What happens when you write the full path explicitely:

  boot cd ofwbootdb /pci@80000000/ide@7,1/cd@0,1/netbsd
