Cold Boot Failure Messages
During a cold boot, the system briefly displays a status line for each driver as it loads, in this
format:
0: Drivername #.##
The line shows a status value, usually 0, followed by the driver's name and version number.
If the system halts at one of these lines and displays a status value other than 0, the displayed
device driver failed to load properly. If such a failure occurs, the driver may need to be
reinstalled. Contact Symbol Technical Support.
