Could anyone please tell me what it means?
"%Error opening nvram:/startup-config (Invalid Checksum) 

          --- System Configuration Dialog ---
Would you like to enter the initial configuration dialog? [yes/no]:

Does it mean that the physical memory (dram or flash) is damaged or
incompatible with the router?

Thank you for your time.
