expansion card for a 2600 series router

[timothy.rose]

I recently got a 2 fastethernet expansion card for my router when I applied the card into the router (yes the power was off) and booted it, the router told me that it does not recgonize the card because of the IOS (which was 12.4.15 (4)) so I upgraded to the latest and greatest 12.4.15 (15) and it still will not recgonize the card. Did i miss something ? please help!

Yes, all the relevant details

Seriously, can you post exact model of 2600 and the module number for the module you are trying to use. A lot of these modules need a 12.2T version to be supported so it may be that you need to upgrade again, but it's not possible to say for sure without knowing the details.
