Good IOS for 2522 router?

dissolved

What is the minimum IOS I should have on a 2522 router ?

Router has:
processor (revision M) with 2048K/2048K bytes of memory and
8192K bytes of processor board System flash (Read ONLY)

I found one at a local swap meet here for $80. It has Version 11.2(11) IOS on it. Is that good enough to pass CCNP exams and do all the commands I need? (frame relay commands etc..)?

Thanks

c2500-is-l.120-24.bin will do all of what you asked.

You may want to consider upping the ram and flash.
