Thanks for the feedback Corey. As far as the tv-out, I don't think  
that is going to be possible to extract it. the rm4100 does not have a  
standard bios. It is a custom designed one for wince and it sucks. If  
you want to check out the project my website is:

http://www.smittys.pointclark.net/rm4100/index.php

There are alot of pics there.
It does have a serial port you just have to use a TTL to Serial  
adapter, just like many cell phones etc. We are in much need of a  
better bios for Linux. That's why I am on a quest for Linuxbios.  
Anyone interested in helping would be greatly appreciated.

Thanks - Joe
