[c-nsp] Memory requirements question

[Paul Stewart]

Absolutely.... just make sure you have enough DRAM though too and you're
fine.... sometimes it's easy to confuse the two...

I've gotten burned when you forget about the IOS uncompressing after an
upgrade and not having enough DRAM to run...;)

If the image fits, it fits.  That's all there is.  Most Cisco routers (I'm
not sure about all 8xx series, thus "most") do not use the flash for
anything but IOS files, and potentially crashdumps - so there is no need to
reserve anything.

The upgrade planner is sometimes just way off.
