Start - IBM 2193 Maintenance Service Manual

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, press Print Screen key, while the screen is
displayed.
PLEASE 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.)
