Can someone explain how this works then?
Where does the image decompress to? The way I understood it, a compressed
image which is stored in flash, decompresses to RAM, then runs from there.
Could 2500's ever Run from RAM? Is this image dependant, I thought a router
was either 'run from flash' or 'run from ram'. Can the IOS change that?
I've used mz images plenty on other routers, but can't find a 2500 image
that is not .bin.
Any replies welcome - I'm off to look into it myself.
Cheers,
Gareth
