not sure you are going to find an image that will fit into that small amount of memory . don't think you can upgrade or even find an image old enough to fit that small of memory.

Good question Mr. Brian,


The point is: I need to install a secondary link between our HQ and a branch. I?m at HQ and this routers is 400 km from here at our branch and I can?t ping/telnet into it.

I sent a console cable and ask for a guy there to connect this at one PC and enable Netmeeting.

So, I checked all configurantion and found that the primary link is HDLC, I can ping just local Ether0, there is no access-list, basicylly and HDLC link.


Regards,

In addition to two Netpro's comment. You also need to know which feature set is required. And what specific feature you require. With the limited DRAM (2M) and unknow flash size. You may able to upgrade to 11.x only. Please more.


Hope this helps.

This maybe hopeless as the oldest IOS I see on CCO and via ftp (ftp-sj.cisco.com) is IOS 11.2. IOS 10.3, 11.0 and 11.1 are there but the only image available was for the 7500 in IOS 11.1. Also I didn't see any 2500 images that would run with less than 4 megs of RAM but I didn't look at every feature set just IP, IP Plus, Remote Access Server, etc.


It's easy to upgrade the RAM (DRAM) on the 2500's as a 16 meg stick of memory should only cost about $5 off of eBay.
