Sorry for the long delay in replying. Apologies if you have already been 
helped elsewhere.

Anyway, this is interesting! And I see you have a patch on ecos-patches ( 
http://sources.redhat.com/ml/ecos-patches/2002-07/msg00003.html ). I will 
get to that eventually, but right now I can say for sure that there is a 
copyright issue.

Normally you would need to provide a copyright assignment to Red Hat as 
per http://sources.redhat.com/fom/ecos?file=47 before we can integrate 
your contribution.

But I also see in this case that your contribution includes code from 
GRUB. This is licenced under the "vanilla" GPL, which is something we do 
not wish to permit in eCos code as it undermines the special licence 
exception text we have.

I see the code also has David Woodhouse's name on it. David, is the GRUB 
code, mentioned in the patch above all yours? And if so are you willing to 
provide it under the eCos GPL+exception as well?

If not, then I fear that we cannot integrate this patch, sorry. However we 
can make it available on the contributions page: 
http://sources.redhat.com/ecos/contrib.html

It could still live in the pcmb package, but perhaps in a separate .inc 
file included by pcmb.inc?

Yes, but obviously there's a chance of a bug :-). Make sure you are using 
the current sources. There should be a "disks" command, as per the 
documentation, and then you can use "load -m disk". If you type "help" you 
should be able to see if your RedBoot image is built to support these 
commands.
