 xM is shipped with a micro SD card containing a demo operating system. To test if it works just click the included micro SD card into the slot, plug in a wired ethernet cable, a USB mouse, a USB keyboard, a DVI-D monitor, and THEN plug in the 5V barrel power cable. (It is important to plug in the power last, because plugging in the monitor while it is powered up can cause damage. <!-- I believe this would cause damage to the port, but I can't remember right now. It might also be dangerous to plug the USB cable into the port while it is powered on. --> Applying power should make it boot up, first showing the BeagleBoard logo in the top of the screen, then an Angstrom loading splash screen, then to a screen saying "Automatic login", and if you do nothing, you should soon be dragging desktop icons around and surfing the Web with Midori.

 '''Be sure to buy at least one additional SD card.''' Currently, the BeagleBoard xM is shipped with a micro SD card included that has an Angstrom demo loaded on it. The demo features the [http://en.wikipedia.org/wiki/Midori_(web_browser) Midori] web browser and a full GUI desktop. Additionally, all of the USB ports work with no additional setup. The demo Angstrom OS is surprisingly fast, even though it might sound like it has a lot of stuff on it. On the demo image everything is set up correctly for the version of BeagleBoard that you bought. Writing your own SD card (even when using a prebuilt image) can lead to a surprising number of difficulties, partly due to the many different revisions of BeagleBoard which exist. It is best if you can simply keep the original card unchanged, and do your experiments on other ones. Be wary of thinking that you can simply back up the information on your desktop machine. While it is certainly possible to back up this information, some difficulties can arise since the card needs to be formatted a certain way Also, it's easy to accidentally only partially partial copy the root filesystem files off of the SD card onto your desktop machine because of the varying permissions which the different files have.

 =Checking everything is working=
 First of all you might want to check it for possible defects.  To do so, connect a 5-pin Mini-USB cable to the board and to a computer at the other end.  If everything's all right you should see one LED light up and, after a short while,
 two more LEDs coming up too.  Also, if you connect some speakers or headphones to the audio output you should hear a burst noise when starting the board. (you won't hear a noise on Rev.C boards, [http://groups.google.com/group/beagleboard/browse_thread/thread/810c8a97f6babe7b/d34fb2870be05602]).  For a more complete validiation of the rev. C hardware, see [http://code.google.com/p/beagleboard/wiki/BeagleboardRevCValidation]

 =Types of BeagleBoard=
-There are two major types of BeagleBoard- the BeagleBoard and the BeagleBoard-xM. The xM was released rather recently, and much of the googleable documentation refers to the original BeagleBoard. The two most major differences are that they have different input/outputs, so they require different cables to plug them in, and the BeagleBoard has flash NAND memory, while the BeagleBoard xM does not, so the SD card used to boot the xM must contain 3 files... MLO, u-boot.bin, and uImage. Original BeagleBoards have u-boot loaded on the NAND flash memory.
+There are two major types of BeagleBoard currently in existence- the original BeagleBoard and the BeagleBoard-xM. The xM was released rather recently. Consequentially, much of the online documentation that will come up on Google searches for "BeagleBoard" refers to the original version, and not the xM. Typically, the word "BeagleBoard", when used alone without modifiers, refers specifically to the original BeagleBoard and not to the BeagleBoard xM. Major differences between the two are:
-The xM also has several versions: including Rev A, Rev B, and Rev C. <!-- I believe that's all, but I'm not entirely sure: there may be some "subrevisions".--> Each of these are slightly different, so make a note of which revision you have.
