If you have no flash memory on this M7i, there is no issue, but I really
suggest adding a flash card for the improved reliability. A 1 GB Compact
Flash card from a major supplier should run less than $50. I think the
last ones we bought were only about $35.

See cluepon for the list of what works. The REs in the M7is seem to take
most cards. The T-series REs seem much more touchy.

I am confused by the comment on firewalls. Can you provide a pointer to
the documentation or more explanation?
