upgrade ios on internal + external flash

Hi,

We'd like to upgrade the ios of a 3640 router.The new ios is about 20M but we only have two 8M of flash.We've planned to put a 16M pcmcia flash.

Is it possible to install the ios on 2 * 8M internal flash + 16M external flash ?

Hi,

Unfortunately, the answer is no. The image must reside on one flash device that is greater than the size of the actual image. So you'll need a 20MB flash card or larger.

HTH,

Bobby
