I'm using Etherboot with the cards.  I bought EPROMS for the cards that
tell the cards to tftp the boot image from my server.  The boot image
loads the kernel and nfs mounts the FS.  I've got this working quite
well, and I even have the 64 nodes up and running.  It's just that this
is a mostly homegrown setup and I'd rather install a "supported" setup.  :-)

Do the Scyld doc's talk about diskless configurations?
