Looks like your flash memory is malfunctionong or missing!?
Explanation: At boot time, the router tries to load the first file it finds in flash.
If nothing is found, the PCMCIA slots are probed for any valid code.
Appearently this is not happening to your router anymore. This raises a few questions as to how this has happened:
What did you previously use to boot from?
Did you perform an IOS-upgrade or have you made any other modification to your flash memory setup or your boot-process?
To come around this, the easiest way is to insert a flash-card with a valid image and let the router boot from that. If this is not available, you have to try and recover the router from any other source (tftp server)
You might even try to re-seat the flash SIMMs.
Do an all-words search at Cisco.com for "recovering flash 3640" for some docs on how to do it.
Well, it is also possible that the flash is there, but the flash image is missing. When at the rom monitor, issue the dir flash: command. Check if it lists any file in the flash. If it cannot, you might have a flash problem. Either way, you might try to use xmodem or tftpdnld to copy another image to the flash and then reboot the router.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
