I do not think it is possible. I have worked with quite a few
CISCO3640's and have never heard of anyone being able to put 64 megs
of flash into the router. Also, I believe the maximum you could put
in the PCMCIA slot is 20 megs, per slot.

I used compact flash cards to upgrade my router flash. 64MB is
supported and you don't need to open up the router. You don't
need to power down the router (I did run across an older version
of IOS the required power cycle to recognize the card.) Plus it
cost less. There are several approved vendors for the CF.

Please could you point me to a device known to work with a 3640?
