How to boot from Flash (If containing 2 Images)

controlcontrol Posts: 309Member
Hi,

If I had 2 different IOS versions in the flash, how would you chose to boot from one over the other? (call them 1 & 2)
If booting from 1 and then I save the config. Would the same config be used if booting from IOS2?
