Like RayeR mentioned, the currently available Intel Galileo/Quark datasheets imply a custom "BIOS"/firmware boot system, similar to the BifferBoards <Info Blog and Project Home> that used RDC x86 CPUs. Last week, Mouser had these Galileo boards for $65 on presale <Mouser Info and Mouse Sale>. Today, they're $70. :/ Their datasheets recommend 5V 3A power but supposedly can run/boot 3.3V at 800mA and 5V at 800mA. Oddly, they list Mac OSX as "Compatible Software" but I assume that means host SW.
