Upgrading flash on a 3845 - which files do I need?
I've run out of room for two IOSes on the puny 64MB CF card that came with our 3845. Couldn't find any info on cisco.com about upgrading flash:/, so I have several larger CF cards lying around and I assume they will work after I put them in the router and reformat them.
Besides the IOS image, which files do I need to save on the new drive? All these tar files are for the HTML interface, I presume, so I don't need them? The config is saved in nvram, which I assume is NOT on the CF card.

A Subquestion: Is it safe to remove the CF card and insert another while the router is running?
I know I could delete the current IOS image on flash:/ and have enough space, but that is living too dangerously.

Thanks to all who replied/ The old "SanDisk Ultra II" card from my old dead digital camera works perfectly.
The CF card was swapped out with the router active, but no one logged in, then reformatted. The manual exhorts one to shut down all "network connections" before swapping out the card, but presumably if no one is logged in the filesystem is not "open" so thee is minimal risk.
