Today I received my Intel Galileo board that I ordered sometimes in October from Mouser.  The shipment date was initially mid November but got pushed back a few times. Anyway, I was planning to toy around with it over the holidays and was thrilled when it shipped December 24th. Galileo must have called Santa and put in a good word.
The board comes in a nice box together with a power supply. I wish it had stand-offs to provide some support when sitting on a table. This would prevent the board from resting on the mini-PCI card slot tips mounted on the back-side of the board. Those tips look like they could easily break off.
Anyway I will try to document the journey to get the board up and running.
For the documentation and software just head over to www.intel.com/support/go/galileo and download the related build for your OS. Intel supports 32/64 bit Linux, Windows and MacOS-X. The release as of this writing is 1.5.3 and gets delivered as a Zip-archive.
Downloading the Windows version and unzipping it with the stock Windows un-zipper produced an error because of too long file names in git related files. Using 7-Zip however completed without a hick-up (see also the Galileo Getting Started Guide) .
The next step is to plug in the power supply and connect the Client-USB port with a micro USB cable to your computer.  Once the Galileo USB port is detected by your computer (it shows up under “Gadget 2.4”) you must install the related serial drive. It can be found in the IDE installation directory under  ./hardware/arduino/x86/tools/linux-cdc-acm.inf .  Now it is time to start the arduino IDE and perform a firmware update. You can find the menu entry under Help->Firmware Update.
