The above U-Boot seems to be a version that's installed in the MBR and
then loads a second-stage program (from where, though?). It's not a
flash rom replacement as far as I can tell -- at least I never did
anything with the flash, and I think before I loaded this disk image,
it was using lilo. I probably still have the original drive that was
in it, with whatever that was booting from.
