Re: Serial adapter
G'day Alan, Thanks for your question. You can find this adapter from Plan Ceibal, or from the OLPC Association, contact mar...@laptop.org. The same adapter works with XO-1, XO-1.5 and XO-1.75. I've not tested an alternative, but http://wiki.laptop.org/go/Serial_adapters does provide the specifications and pinout.

Re: 11.3.0 -> SD Card?
If Mikus is around to help, his technique, utilizing symbolic links, yet keeping the base install O/S on the internal is quite elegant. It can easily utilize swap too.

Serial adapter
Hello, I'm from Uruguay... Where can I find this adapter? http://wiki.laptop.org/images/2/27/Serial_adapter_3.png Only I find similars in e-Bay...

Processing which can be taught to older kids is about 80MB when unpacked (minus JRE)) Another reason is that if too many sectors on local flash become bad, the ability to run from SD is a big plus - as we all know flash storage has a read-write lifespan and web-centric behavior these days tends to be cache-heavy on read-writes (browser cache, streaming video, audio, etc) As an aside, I'd like to give kudos again to you guys who keep making this happen -- the advantage of the XO over something like Android is that you can actually use it to build apps to run on itself (beyond Javascript), and nowadays, I think it's what separates "devices" from "computers" given that devices these days have insane amounts of horsepower (and apps still manage to run like crap). I think most average developers these days don't know how to optimize stuff for performance (or even care for that matter) and have gotten lazy from Moore's law. It's become more relevant today than ever now that computing has started shifting more to mobile space and it's becoming the norm, and lazy reliance on Moore's law is a vicious cycle which has a horrific effect on the environment & sustainable computing (e-waste, power crisis).

11.3.0 -> SD Card?
Congratulations on the release guys! Q: is there a way to install 11.3.0 on an SD card for the XO-1 like with alternate OSes on XOs instead of using the local flash storage? Unfortunately, what's left over from the 1GB is barely enough anymore once people putting a lot of content on their machines like video. With the price of SD cards being relatively more affordable in SE Asia, it's an ideal solution.

Thanks to some great work by Paul Fox the previous problems with q2f04rc should now be fixed.
