Problem determination tips
Because there is a large variety of hardware and software combinations that can be
encountered, use the following information to assist you in problem determination.

v Verify any recent hardware changes. See “Hardware considerations” on page
v Verify any recent software changes. See “Software considerations” on page 133.
v Verify that the BIOS is at the latest level. See “BIOS” on page 133.
v Verify that the drivers are at the latest levels. See “Drivers” on page 133.
v Verify that the Configuration matches the hardware. See “System resource
v Verify that the Diagnostics diskette is at the latest level. See “File updates”.
As you go through problem determination, consider these questions.
v Do diagnostics fail?
v What, when, where, single, or multiple systems?
v Is the failure repeatable?
v Has this configuration ever worked?
v If it has been working, what changes were made prior to it failing?
v Is this the original reported failure?

Important:
To eliminate confusion, systems are considered identical only if the following are exactly
identical for each system:
identical for each system:
1.
Machine type and model
2.
BIOS level
3.
Adapters/attachments (in same locations)
4.
Address jumpers/terminators/cabling
5.
Software versions and levels
6.
Reference/Diagnostics Diskette
7.
Configuration options set in the system
8.
Setup for operation system control files
Comparing the configuration and software setup between “working” and “non-working”
systems will often resolve problems.
