Do 2651 Cisco Routers have any flash memory built directly on the motherboard?

The reason I ask is that I am looking at upgrading a few 2651 routes and the cisco documentation is open ended. Do these routers have 16 meg flash build onto the board? If so, to add another 32 meg would mean just tossing in a SIMM correct? I am looking for some documentation of where and if this router has built in flash. Thanks.
Soul.. is there any documentation on this?

Reason I am asking is because I really dont feel like doing these upgrades and losing the IOS on them.

I have done Xmodem in the past and it hurts lol. Im told you can TFTP from Rommon on this router but I do not understand how. Can you assign an IP to an interface in Rommon if you lost your IOS?
Clark.. this router doesnt use flash cards……..

   Yes the 2651 does have built in 16MB and they’re only upgradable to 48MB. There’s 1 upgrade bank for the additional up to 32MB.

   Clark, these are older routers and don’t use the flash carts like the new(er) cisco’s

   Cisco flash cards aren’t like any other computer memory I have seen, they almost look like a compact flash memory card.
