One of them is refurbished XO 1.0 and the<br>other is the newer XO 1.5. I need to reflash the new XO 1.5 with the new<br> OS but have been facing some problem. I downloaded the latest OS206.zd<br>from <a href="http://build.laptop.org/10.1.1/" target="_blank">http://build.laptop.org/10.1.1/</a>. I put up both the files in the top<br>level of a USB stick. Although, the image was found by the laptop, I am<br> getting this message on startup. Below is the description of the<br>problem, if you could suggest something?<br></blockquote><br></div>I have no experience with the XO 1.5, but:<br>as the error messages is related to block sizes, I would first check the integrity of the image (using md5sum). If you have already done it and you are still experiencing problems, I would try inserting the usb stick when the machine is off and then booting it while pressing the four game controller keys on the right of the screen all together. This worked and allowed to bypass some problems on the XO 1. <div><br><br> <blockquote style="BORDER-LEFT: rgb(204,204,204) 1px solid; MARGIN: 0pt 0pt 0pt 0.8ex; PADDING-LEFT: 1ex" class="gmail_quote">The second XO will allow me to create a mesh network between the two XO’s.<br></blockquote><br> </div>Nice. You can also use SOAS on the devices in order to get exactly the same environment. You don't actually need to use a mesh network: the XOs automatically "talk" to each other when they are connected to the same access point. This structure:<br> <br>XO -- AP -- XO<br><br>is the same as<br><br>XO -mesh- XO<br><br>and requires less efforts, both from you and from the cpus. <div><br><br> <blockquote style="BORDER-LEFT: rgb(204,204,204) 1px solid; MARGIN: 0pt 0pt 0pt 0.8ex; PADDING-LEFT: 1ex" class="gmail_quote">I was collecting some material (Common objects, Holiday, Class,<br>Workplace etc.) yesterday for the activity’s interface and have been<br> playing around with the XO's to get familiar with their functioning.

I know you prefer working with C#, but you should better ask them if there is something you can do to integrate their job, instead of replicating it. <div><br><br> <blockquote style="BORDER-LEFT: rgb(204,204,204) 1px solid; MARGIN: 0pt 0pt 0pt 0.8ex; PADDING-LEFT: 1ex" class="gmail_quote">And, how's it going in Greece?<br></blockquote><br></div>I am going home today. Actually, I am writing this email from Athen's airport. The conference was not so good, the major advantage in coming here was the weight of the publications they produce. But I was assigned to a session where my work was totally unrelated to the other presented papers. I still enjoyed my stay in Corfu, which is a terrific place to go on holiday.<br> <br>Ciao!<br><font color="#888888"><br>Andrea<br></font></blockquote></div><br></div></div><br></div><br>
