[syslinux] Is there a howto for using redboot to kickoff apxelinux boot?

Geert, to answer your PS.
I'm trying to bring up Rocks on my little cluster here. Rocks, depends
on a PXE type mechanism for node installation. Unfortunatley, my nodes
don't support a CD_ROM for normal kickstart installation, so I am
resorting to using a PXE boot method. The other unfortunate is that
they have have redboot on them as opposed to .... almost anything else
that supports PXE. :(
So I am trying this and that to get this little cluster to play with OTS
cluster software. It's a little frustrating.
I'm going to look into the Etherboot project as you recommend. In fact
looking at my dhcpd.conf file I see that if the client reports as a
etherboot client, it still gets handed the pxelinux.0 file so there must
be some high synergy there.
Thanks for your help.

:-) nobody said it would be easy

My guess is that redboot binaries have another header format,
then the pxelinux.0 has.
An simple check would be doing
After prepending pxelinux.0 with the redboot header info,
you will mostly likely will be missing PXE code in the redboot boot ROM.
My advice is to contact the people from the Etherboot project,
if you want to continue with "pxelinux.0 on redboot"
I wonder why to load pxelinux.0 to load a kernel,
where redboot can load a kernel at once ...
