The board is a Kino LX800, AMD GEODE 500mhz, sata/pata, onboard amd video, onboard realtek 8139 ethernet.
This board should be able to meet your needs. The CPU and chipset are well supported in LinuxBIOS v2. mainboard/amd/db800 would be the place to start. We would be very interested in seeing some profiling of LB and if there are any places where we could optimize for speed. Please post any specific questions or results.
