How to Diagnose Combined FRUs: If an adapter or device consists of more
than one FRU, any of the FRUs might cause an error code. Before replacing
the device or adapter, remove the FRUs one by one to see if the symptoms
change.
If a newly replaced FRU does not correct the problem: If you have reached
this point of the check procedures and were instructed to replace a FRU but
doing so did not correct the problem, reinstall the original FRU and go through
"Start" again.
If you want to print a copy of a BIOS Setup Utility screen to an attached printer,

READ THE FOLLOWING:
Human Error is a cause for concern when applied to check procedures. It
exists in every first time set of analysis procedures. It is therefore
essential for effective and time-efficient servicing that each stage of
every procedure be verified. (For example: When a symptom is found, or
when a symptom appears to have been cured; the preceding steps
should be repeated for accuracy of analysis.)
