Cisco 4700-M+

In a 4700M does the Rxboot flash simm count towards flash memory. Explanation to follow.

I have a 4700M and want to upgrade IOS. However, I am not sure if I have enough memory. There are three slots available: one for Rxboot flash and two for flash. Currently I when I do a sh ver I see:

4096K bytes of processor board System Flash

4096K bytes of processor board Boot Flash

The boot flash has nothing in it and the IOS 12.0(3)is installed in the system flash.

Can I upgrade to 12.1 which requires 8Mb of flash?

If not what is the difference between boot and system flash in this particular router? I am stumped!

Re: Cisco 4700-M+

In short the answer is no.

The bootflash is there to hold a boot/failover image only, it cannot be aggregated into the system flash to allow for a larger IOS image to be installed.

You will need to purchase another 4Mb flash before you can install even the IP only featureset of 12.1. Sorry!
