Were are the dependencies for your miboot package, BTW?

I don't know if I mentioned this before, but I'm building now my kernels
with kernel-package and what I've been compressing to get onto the
miboot floppy is the one that ends on the /boot directory (stripped or
not, I can't remember---and I'm not using a ppc right now).

But just editing the System.bin file with appropriate commands work
quite well (for instance, for enabling the l2 cache via the l2cr

I see no problems with that if you just want to get something
functional.  OTOH, it probably doesn't help for further development of
boot images, I agree.

Perhaps because he wants to understand the issue first and then do
things "the right way"?

I think that he is concerned first in getting something working and then
doing variations on that.

I have many things compiled into my own (oldworld) ppc kernel, including
two filesystems (ext2, ext3), the nic driver and other things.

Have you checked the config file that I posted to Andrew Morton some
time ago? It should be on the lkml archives (again, I would send it now
if I were in front of my PowerMac).

Hope this helps, Rogério.
