forgive me for being new, but if the chip is proprietary, can drivers still be written easily or is it more of a guess and check strategy? Also I will be able to help out with any kind of development that needs help after the first of January, 2004. I have to admit that I've never really worked with building drivers before, but I'm very interested in learning how to write drivers and I will learn what is necessary to do it. Please let me know where you think I can help out the most. derrick -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
