Feedback

Feedbacks from users are realy important. This is a alpha version written through a reverse engineering proccess of PC97551 embedded controller (EC), present in my Acer Aspire 3003LCi. Aspire300x can work on models that have this EC (maybe). If you are running on other models, let me know about it.
