For those makers and home engineers, here's another Arduino offering in x86 32-bit flavour: Arduino/Genuino 101 It contains a low-power Intel Curie module with the Quark processor inside. Of course, it's for the prototyping and embedded systems, so the program memory and the RAM will be much less compared to the Galileo. However it will be available at early 2016. I'm wondering can I still write a BIOS in there for practising? We don't have much x86 microcontroller there, so this can be the nearest (and the most accessible) one!
