Problem determination tips
Due to the variety of hardware and software combinations
that can be encountered, use the following information to
assist you in problem determination. If possible, have this
information available when requesting assistance from
Service Support and Engineering functions.
Ÿ
Machine type and model
Ÿ
Processor or hard disk upgrades
Ÿ
Failure symptom
– Do diagnostics fail?
– 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?
Ÿ
Reference/Diagnostics Diskette Version
– Type and version level
Ÿ
Hardware configuration
– Print (print screen) configuration currently in use
– BIOS level
Ÿ
Operating system software
– Type and version level
Important
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 Reference/Diagnostics Diskette
(version)
7. Have the same configuration options set in the
system
8. Have the same setup for the operation system
control files
Comparing the configuration and software set-up
between “working and non-working” systems will often
lead to problem resolution.
