When asking for technical help at the very least let us know the version of firmware you are running.Cliff's Calibration (Mapping) Guide is a MUST READ: http://www.vemssupport.com/forum/index.php/topic,97.0.html
Rob : VemsTune only works in Windows, so I don't get where you think Linux will work. I'm not sure it will work with Windows CE, never really had a reason to try.It works well enough on an Asus EEE 901 with Windows XP, that's a pretty small screen and slow cpu with little memory as standard. These days most netbooks have better specifications than that.
