I'm glad to hear your XO is working again. While it's working, I
would highly recommend getting a developer key so that if you have
similar problems you can make a custom SD card to solve them. It's
quite a pain to get a developer key if you can't boot your XO.
To get a developer key, follow the instructions at
http://wiki.laptop.org/go/Activation_and_Developer_Keys#Getting_a_Developer_Key_for_your_Running_XO_Laptop.
Let me know if you have any questions about copying
/security/develop.sig to an SD card. You will need to do this to make
sure the developer key is still accessible if your XO won't boot.
