This means that if you have today XO-1 or XO-1.5 laptops you can purchase an upgrade kit that will turn it into an XO-1.75.It does require that you perform the motherboard replacement, but the savings can be significant. Kits have been available as spare parts for deployments to purchase.In that post on OLPC's blog Martin Langhoff (OLPC Association's Senior Software Architect and Technical Director) writes: Part of our focus is to support deployments that have made a long term commitment to work with us.When we have new models, we work hard to provide them as an upgrade.Upgrading an XO-1 to an XO-1.5 or higher motherboard requires the insertion of a small metal bracket to hold the WLAN card.The XO-1.5/1.75 chassis are mechanically identical. Upgrading an earlier laptop to an XO-4 motherboard will require a small rubber piece inserted to change the size of one chassis hole from USB to micro HDMI.The firmware on the XO runs when the power is turned on. If the laptop is secured, or if the X game key is held down, it looks for boot/on all available storage devices; internal storage, SD card, and USB drives.If a is found, the firmware checks to see if the cryptographic signature of the file matches the OLPC keys, and if the version is later than itself.
To upgrade your firmware automatically, please upgrade the operating system.
Your feedback is important for us to support you and offer the best experience with the XO devices: problem reports and suggestions are greatly appreciated!
Warning: This will erase all the existing files on the laptop: make sure you backup important items first!
Choose the release you want to upgrade to from the Releases page and view its release notes, or follow the links in the Software box on the right to the latest XO version, and follow the instructions.
