Errors reported against NVRAM can be
caused by low battery voltage and (more
rarely) power outages that occur during
normal system usage. With the exception of
the 25A8 0000 error, these errors are
warnings that the NVRAM data content had to
be reestablished and do not require any FRU
replacement unless the error is persistent.
When one of these errors occurs, any system
customization (for example, boot device list)
information has been lost, the system may
need to be reconfigured.
If the error is persistent, replace the primary
I/O book,
