Sounds like you're netbooting. There are a few things. Using the niot cmd,
make sure everything is set up correctly. Using the 'env' cmd, make sure
network PREP-boot (or something like that) is turned on.
I take it you're using the code in the linuxppc_2_5 right? Make sure the images
in arch/ppc/boot/images/zImage.pp3 is the kernel actually being transferred to
your board.
Also, not that it should matter, but I used the ppc_82xx tools.
