Ok, its been a busy week and I've made more progress. Touchscreen is now working and calibrated without a pointercal file. Then I discovered wifi was broken and this has taken some time to figure out, currently I have a work around and have wifi working but the fix has to be applied after each reboot.
The bad news... Flash 10.1 installs but crashes the browser, rendering it unuseable. I have read up, this is a common problem without fix!
Going back to work tomorrow so not much time to play with this anymore! I will post boot and system images sometime this week of progress so far (I think I will have a wifi fix by then)
