I'm an idiot! I have since read the playground/OF obp-tftp package
specification and realized that even though the machine knows the IP
addresses and the boot file name, I still need to be running bootpd.
So now I have the network boot mostly working. Not entirely because the
TFTP transfer times out (strace'd tftp exits on the server after 5 x 5
second retries, but the RS6K keeps sending UDP packets?!) with the 2MB
PReP boot.bin, and all other images transfer but behave the same way as
the DOS floppy boot: PReP kernels don't appear to even start and CHRP
images hang after "copying OF device tree..." (sometimes before "done").
Help?!
I think I better cross-compile a PReP kernel without the ELF header
stripped...
