Hardware conguration
Print (print screen) conguration currently in use
BIOS level
Operating system software
Type and version level
Note: To eliminate confusion, identical systems are considered identical only if they:
1. Are the exact machine type and models
2. Have the same BIOS level
3. Have the same adapters/attachments in the same locations
4. Have the same address jumpers/terminators/cabling
5. Have the same software versions and levels
6. Have the same diagnostic diskettes (version)
7. Have the same conguration options set in the system
8. Have the same setup for operating-system-controlled les
Comparing the conguration and software set-up between “working and non-working” systems will often
lead to problem resolution.
