Because of the variety of hardware and software combinations that can be
encountered, use the following information to assist you in problem determination. If

Support and Engineering functions.
v
Machine type and model
v
Microprocessor or hard disk upgrades
v Failure symptom
– Do diagnostics fail?
– What message appears in the diagnostics log?
– What, when, where, single, or multiple computers?
– Is the failure repeatable?
– Has this configuration ever worked?
– If it has been working, what changes were made before it failed?
– Is this the original reported failure?
v
Diagnostics version
– Type and version level
v
Hardware configuration
– Print (print screen) configuration currently in use
– BIOS level
v Operating system software
– Type and version level
Note: To eliminate confusion, identical systems are considered identical only if
they:
v
Are the exact machine type and models
v Have the same BIOS level
v
Have the same adapters/attachments in the same locations
v Have the same address jumpers/terminators/cabling
v
Have the same software versions and levels

Comparing the configuration and software setup between working and non-working
computers will often lead to problem resolution.
