Using cisco flash card for ''startup confg'' backup??

Hello,
I have a case like this:
3 Cisco routers on remote locations(A,B,C) (model 1841 with 64MB Flash card). On the remote locations I have people who have physical access to routers and nothing else (they can physically replace the routers or Flash card). They have one backup router(on location A) in case something happens and they have to replace 1 of 3 routers in production.

Is there a way that I could use Flash card from the backup router to transfer the startup-config (that I need) to backup router.

I have been doing similar thing with Nortel router, but on the Nortel routers ''config'' is on the PCMCIA card (so the router boots and gets config from the same card).
If the problem was with the PCMCIA card I would do this. Take the new card,
ask the people to put the new PCMCIA card in a working router, transfer the config, put it out back in the place of the broken and restart the router.

tnx

Save the config to flash and then transfer it over on the next router. Same you would do with the Nortel basically.

you could do copy startup-config flash: (use correct flash for the card) swap to new router copy flash

name of saved config file) statup-config reboot router to enable config (use the repplace config command to apply with out reboot.)

Tnx for the answers... I have been considering the solutions that you provide before posting.

I'll try to explain more:

In Nortel's case I can put config on the PCMCIA card and then put that card in router and it will boot up with the config from the card. So I don't need access to a router..I don't need to do copy flash to startup...

In this case with cisco I can have a startup-config stored in Flash but I don't have access to the backup router so I can't do copy flash: nvram:

Is there a way to tell the router: search the startup-config in the Flash and use it.

What I want is just to copy the startup-config to Flash card. Put that Flash card in backup router. The router boots and uses that copied startup-config without any intervention from me or anyone else..

I've done this before on the 2800 series routers - Try adding "boot config flash:FILENAME nvbypass" to the config (assuming the command is available on the 1800s).
