Chapter 6 Troubleshooting the System Hardware
Error Symptoms
–
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
• Have the same configuration options set in the system
• Have the same setup for the operating system control files
Comparing the configuration and software setup in working and nonworking systems might help to
resolve the problem.
