I put a slim .config that I have used to boot an oldworld (PMac 9500
180MP) at <http://www.ime.usp.br/~rbrito/config-2.4.23-pre5-ben0-1.ow>.
It has few options turned on, but serves as a proof of concept for
booting a 2.4 kernel on oldworlds.

when gzipped, takes about 1.5MB, which is obviously quite a lot for a
floppy. OTOH, it boots and works ok with quik on said oldworld.

If some support is removed from it, then I'd guess that one could
squeeze a kernel that works with both oldworlds and newworlds into a
boot floppy with miboot. It seems that miboot takes about 100-150kb of
the boot floppy.

I can provide the image of the floppy I made, if there is any interest
in it (based on woody's boot floopy).

Hope this helps, Roger...
