Frequent asked questions:

I want to install LINUX on my HTPC based on S21T. Are there Driver for Linux available to drive IR and Touchscreen?

Linux touch screen drivers can be downloaded from here: http://www.hantouch.com/Driver/list.asp?Type=DR1
The S21T is pre-installed with the IR221 module that will only work with Vista. If you are using Linux you need to purchase the IR210/IR211 which works using IRTrans (www.irtrans.com)
