– What, when, where, single, or multiple systems?
– Is the failure repeatable?
– Has this configuration ever worked?
– If it has been working, what changes were made prior to it failing?
– Is this the original reported failure?
vDiagnostics version
– Typeand version level
vHardware configuration
– Print (print screen) configuration currently in use
– BIOS level
vOperating system software
– Typeand version level
Note: Toeliminate 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 configuration options set in the system
8. Have the same setup for the operating system control files
Comparing the configuration and software set-up between “working and
non-working” systems will often lead to problem resolution.
