– Print (print screen) configuration currently in use
•
– BIOS level
WAAS system software type and version level
To eliminate confusion, identical systems are considered identical only if they meet all these conditions:
• Are the exact machine type and models
•
•
•
•
Have the same BIOS level
Have the same devices or attachments in the same locations
Have the same cabling
Have the same WAAS software versions and levels

Comparing the configuration and software setup in working and nonworking systems might help to resolve the problem.
