– BIOS level
• Operating system software
– Type and version level
Notes: 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 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.
Symptom-to-FRU index
The Symptom-to-FRU index lists error symptoms and possible causes. The most
likely cause is listed first. Always begin with “Service checkout” on page 69. This
index can also be used to help you decide which FRUs to have available when
servicing a computer. If you are unable to correct the problem using this index, go
to “Undetermined problems” on page 73.
Notes :
• The Symptom-to-FRU index is not specific to any machine type and are applicable to
all ideacentre computers.
• If you have both an error message and an incorrect audio response, diagnose the
error message first.
• If you cannot run the diagnostic tests or get a diagnostic error code when running a
test, first diagnose the POST error message you receive.
• If you did not receive any error message, look for a description of your error symptoms
in the first part of this index.
