The deployments' XO Operating System
Dextrose is a Sugar distribution for the XO-1 and XO-1.5 jointly developed by Activity Central, Paraguay Educa, Plan Ceibal and Sugar Labs in collaboration with the OLPC and Sugar community.
Our focus is stability and usability in the classroom, but we've also merged some new features contributed by deployments and freelance contributors.

Dextrose 1
This is a Release Candidate. This build has been tested in two classrooms for over one month. We believe them to be stable and ready for general use. If no further issues are discovered, the RC will become our final Dextrose 1 release.

- Drop to the "ok" prompt by pressing ESC repeatedly during boot
- Type the command:
copy-nand u:\osNNNpyg.img
followed by ENTER - Wait for the display to fill in with color and the "ok" prompt to return
- Type the command
reboot
followed by ENTER - The XO will reboot, finish writing, reboot itself, and take you to the naming and color choice process
- During the reboots, keep the charger connected to allow OFW to self-update

Using Dextrose in your deployment
A few customizations make this image somewhat deployment-specific:
- Limited language support: in order to save space, only English and Spanish translations are included.
- Image is signed with the Paraguay deployment keys. Laptops from other regions need to be unlocked in order to load this image.
- The software update control panel icon checks for new activities on the Paraguay Educa wiki.
- The Browse home page contains the Paraguay Educa logo and links to our website.
We may find the time to release slightly modified images to meet the needs of deployments interested in upgrading.
More importantly, we're happy to help other deployments produce their own OS images independently of us, thus exploiting the Freedom #1 provided by Free Software.
