I recently purchased an LE1600 off ebay and installed XP on it. It seems to run fine and is in perfect condition except for the following: 1) Buttons do not work: When I open dashboard and click pens and buttons options nothing opens. The pen calibration says it is missing tabcal.exe 2) WIFI does not work: Installed driver but it says: adapter problem, driver not installed Note: LAN installed fine but also continues to show up as missing in device list, also in missing devices, there is 1 unknown device SPECS: XP SP3 (with critical and LAN updates), Latest A12 BIOS, P1.60g , 1.49g ram (only 1g installed) Installed drivers: -Dashboard V4007 -Motion Button driver 3118 -WLAN driver v105175 -LAN NIC -Bluetooth (working) -Wacom Tablet PC driver: ISD_DualTouch_711-12 (is this the best one?) Also is there any way to emulate OpenGL 2.0 if mine only seems to run 1.4? Thank you!
