[c-nsp] Image in slot0: vs. flash after reload

[John Neiberger]

I'd have to save the config for that to work. The problem with that is
that the image that is running at the moment is missing some features
that the startup config requires. If I add a boot variable and save,
I'll lose all the commands related to those features.

I still don't understand why the router booted to slot0: instead of
flash. If that is standard behavior, then why was it running the image
in flash before the reload?

Simply write boot system slot0:c3640-jk9s-mz.122-31.bin the only thing

that you need to change is name of ios depend on what you have , yes
you 
a right there is no explicit command and you can't see in help context
?
