I have a Cisco 2811 at a client site that will not boot. I powered down to work on the UPS and when I powered the router back up I get this error message on boot up&
Error : compressed image checksum is incorrect 0xAAF13B7D
Expected a checksum of 0x39AC9B1D
*** System received a Software forced crash ***
It brings me to a rommon 1 > prompt.
I have tried booting from the IOS image of the flash but no go.
Any ideas for me???
