Looking at page 5 of the manual for this mobo (http://www.viaembedded.com/product/Download.jsp?motherboardId=3D241), it looks like there is a VT1211 super I/O chip connected to the VT8235 southbridge.=20 The GPI/O is nowhere to be to been seen on this drawing, but the webpage for the VT1211 (http://www.via.com.tw/en/products/peripherals/super-io/) lists "56 General Purpose I/O Pins" My guess would be that that's what you're looking for. You'd have to talk to VIA how the 8 pins on the mobo are connected to the VT1211. VIA has released an IrDA driver for the VT1211, but it is Linux-only and binary-only. You could write VIA and ask them to release enough documentation to allow a driver for the digital I/O pins to be written. Good luck.
