Please use your SBIGDriverChecker program to update the SBIG camera drivers. Users who have STX / STXL cameras and are using an AO-X should also update their camera firmware. Do not upgrade your firmware unless actually necessary - there is some risk of bricking your camera. If the camera is bricked you will have to send it to Bill Lynch for service. Important: Do not interrupt the firmware upgrade process. If the Driver Checker goes "not responding" during the firmware upload process, this is normal. Under no circumstances should you stop the program, disconnect the camera, or power off the camera until the process is complete.
