How do I get Linux to request calibration for a system that has already been calibrated?

There are three ways to do this--they all have to do with deleting the file called "pointercal":

  • Use the command line over the serial port to delete the file called "pointercal" in /etc/
  • Delete the file "pointercal" in /etc/ from the file viewer window once linux has booted
  • Put the CompactFlash card in a reader connected to a PC and delete the file called "pointercal" in /etc/
