NVRAM stands for "Non Volatile RAM". When doing an internet search, I came
up with this:

and this:

...from the Dallas semiconductor company. This is a quote from the first page:

A good short definition of NVRAM was at the ZDnet Webopedia at
http://www.zdwebopedia.com/NVRAM.htm
which states in part that this memory retains its contents after power is
turned off (the reason it's called Non Volatile, as opposed to most other
types of RAM, which are volatile and lose their contents after power is
shut off.)

Unfortunately I too could not find a lot about what your error message
could mean, but perhaps another list member can enlighten us both on this.
