Re: IOS upgrade

You should able to use two flash RAM as a single storage. However, you have to ensure the flash memory you get is supported by the hardware. Is it bought from Cisco or 3rd party ? If it is 3rd party, please check the compatiblity.

Then you may find there is partition command in the router. Try to remove the partition command then check the flash size.

However, if you already have one 8M flash, the 5M IOS should be able to put into the flash w/o require additional flash.

You can use "sh ver" to verify the TOTAL flash size. And use "sh flash" to show the flash status.

Hope this helps.

Re: IOS upgrade

I made a mistake. This should be the question.

How can I load IOS which 15mb long, on 2500 series router that has two 8mb memory sticks? These sticks are both compatible by Cisco hardware.

Re: IOS upgrade

Hi

In general the router will show you the combined space available...Is it not in your case?

Can you give the " show flash" or "dir" output after installing both the flash sticks.

Re: IOS upgrade

You need to unpartition the flash. From the config mode issue the command 'no partition flash' and it should make the flash just one partition.

The router may prompt you need to erase the flash before unpartitioning. If it does then issue the command 'erase flash:1:' and 'erase flash:2:' from the privilege exec mode and then do the 'no partition flash.

HTH,

Re: IOS upgrade

Try to backup the running IOS image before erase it. You may need to fallback to the original IOS.

Then enter "no partition flash" to remove the parition then you will have 16MB flash. Link for your reference.
