OK so I was having a problem with My mouse jumping all over the screen from the GPS and the serial ballpoint driver. the Panasonic Registry patch was not working for some reason so I had to let the mouse jump all over the screen and try to disable the serial ballpoint driver with the stylus. If you disable the GPS in the bios then the ballpoint driver will not show up so you can disable it. so it has to be done with the Mouse going crazy. I have found a better way around this and figured i would share. First boot into the bios and disable the GPS. Save the changes and boot into windows. Next follow these Steps: Right click My Computer Select Properties Select Advanced Tab Select Settings in Startup and Recovery Select Edit Add /NoSerialMouse (this is case sensitive) to the line that looks like: multi(0)disk(0)rdisk(0)partition(2)\XP="Windows XP" /fastdetect so that it now reads: multi(0)disk(0)rdisk(0)partition(2)\XP="Windows XP" /fastdetect/NoSerialMouse File - Save Exit Reboot Boot into bios and re-enable the GPS and save and exit. Now the serial mouse driver will not load and you will not have any red x in the device manager. Hope this works for other's too. James
