2620 Memory /Flash Requirements for Multilink Frame Relay (MLFR)

Per the ISP, our Cisco 2620 with 2 t1 WIC's should work with their MLFR product as long as we have a version of IOS which supports MLFR, such as 12.2.   Running a Cisco tool on show version the result is:

INFO: This device has 26624 K available for main memory.
INFO: This device has 6144 K available for IO memory (shared memory).
INFO: This device has a total of 32 MB of RAM installed.

Looking at the Cisco software advisor correctly at ,

Am I correct if I add a 16mb flash module I can run something like IOS 12.2 or 12.2M or 12.2XG  (all require
48 + 0 = 48DRAM and   16  FLAS) with the MLFR feature set?  
OR wait....is the 8mb of flash subtracted out and the result is only 40MB RAM ?  Any chance there is an earlier IOS which supports MLFR?  

Bottom line, what is the minimum IOS I need and what memory do I need to ADD to the 2620 to do this?  (beginning to get confused at IOS features and requirements).  Due to budgets, memory is ok to purchase but we need to reuse this router and can't purchase any new modules or routers for this.

If the requirements are 48 megs of RAM, and 16 megs of flash, that is what you need, and don’t add or subtract one from the other. The RAM is where the ISO loads on boot to execute, and the flash is the routers equivalent of a computers hard drive, and the IOS is the equivalent of a PC’s operating system, which is stored on the routers flash memory.

So we know you have only 32 megs of RAM, so you will have to ad more memory. As for flash, you need to do a “show flash” at the router command prompt. At the bottom of the output you will get a line like this “16384K bytes of processor board System flash (Read/Write)”, hopefully it will say 16 megs like this, or higher, if not you will have to add more flash too.

PS You can RAM and flash pretty cheep on Ebay if you are looking for a cheap upgrade.
