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.
 Machine type and model
 Failure symptom
– 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?
 Reference Diskette Version
– Type and revision level
 Hardware configuration
– Print out (print screen) configuration from system
partition or Reference Diskette currently being
used.
 Operating system software
– Type and revision level
– OS/2 SYSLEVEL Command
 Software setup (appropriate to the software)
 CONFIG.SYS
 STARTUP.CMD
 AUTOEXEC.BAT
Important
To eliminate confusion, identical systems are
considered
identical only if they:
1. Are the exact machine type and models
2. Have the same adapters/attachments in the
same locations
3. Have the same address
jumpers/terminators/cabling
4. Have the same software versions and levels
5. Have the same Partition/Reference Diskette
(version)
6. Have the same configuration options set in the
system
7. Have the same setup for the operation system
control files (Config.Sys, Autoexec.bat,
Startup.Cmd., etc.)
Comparing the configuration and software set-up
(Config.sys, etc.) between “working and non-working”
systems will often lead to problem resolution.
