Thank you *blush*.

Well it still needs a litte editing and proof reading yet before mass 
consumuption.  I'd like to get some more info on all the config options.

I also need to merge it with the current FAQ.  Ron is that available in 
text form?

Also Perhaps all the board owners can take a small break from hacking 
code and pick a few options they feel are important, write a small 
description and send them my way.

Perhaps it is already and I just don't know how to use it.  Currently I 
had to manually do the math for my rom size and payload size so that the 
result would match my rom part.

Sounds great.  Would you like to try and code that up?
