You need to understand how to make LoLo scripts. It involves making a config block with "config CREATE S" I think and then "config <filename> <size>". There is a guide to creating LoLo scripts and such in the M5329 documents so I would look there.
I am loading stuff in from a compact flash card so I have mount the compact flash card first. Now getting Linux to boot from LoLo is by no means obvious and I figured out how to do that in this forum post
