    I'll join in the general chorus here. I had one of the very early
    soekris boxes and found it to be a gem. If a 5x86 133MHz processor
    meets your needs, you'll like it a lot. I haven't tried the net4801
    board, but I've worked with other Geode designs and if you need more
    cpu, that'll probably do. Good luck.
