Unfortunately, the SD reader is busted on that motherboard. Still, success: It charges batteries and runs off them just fine. I booted an SD Ubuntu EEE install disk using my Palm phone as a card reader (slow). I filed my nails while this loaded, and had to re-enable the card reader software early on to get the install to keep going. Wow, shorter nails help a lot with typing on this thing.
One of my mods will likely be to put in a working SD reader.
