I am having problems upgrading the IOS on my 2600 router. My problem is :
Currently I have a 2600 with 16mb on board SIMM memory and 32 Mb DRAM. I am looking to upgrade to the latest 12.3 IOS and have therefore bought and installed 32Mb of SIMM.
However when I try to install the IOS it fails and it seems that the router is not using the additional memory I have installed. If I try an IOS smaller than 16Mb ( i.e. onboard SIMM memory ) it works well but if I try to load the new IOS which is just short of 17MB it fails.
What am I doing wrong ? Do I have to issue some commands that instructs the router to load the image on the 32MB simm ?
n.b. when I check in sh ver it shows I have 48Mb installed (16 + 32 ) so I am confident the new memory is good.
I have also swapped out the 32Mb simm out so as to confirm that the ios's are loaded on to the onboard memory and not the new.
How do I force the router to use the extra memory ?
