I have a 3660 router and need to upgrade the IOS. The new version is 29 Mb large and I have only two pcmcia flash memories with 16 Mb each.
My question is: "Is it possible to use them as one only?"
Attached is the show version with actual informations.
The previous poster is correct.
You can't combine the flash, internal or external, to make one large capacity flash card. The IOS can't be stored in multiple flash cards. If upgrading the flash card isn't possible you can have the router boot off of the new image via TFTP protocol from a server on the network.
