Not much! You can run 12.x code on the 4000s, but the semi-modern stuff like Fast Ethernet and ATM modules started with the 4500 series.
Concerning the 4000, the maximum I have seen from the factory of the EPROM chip type FLASH board is 8 Megs and RAM has always been capped at 16 Megs. Around Y2K timeframe, I was contracting for a large government agency (with a lot of 4x00 routers) and we received Cisco SmartNet upgrade kits that provided us the ability to use (2) 8 Meg 2500 series FLASH sticks (new style FLASH board) and also included replacement 10.X boot ROMs. This really did very little for the routers, since the feature rich IOS needed 32 Megs of RAM (which is where the 4000M comes in). The 4000Ms are 16 FLASH and 32 RAM limited. All the best!

[7:70369] Hi, Does anyone knows how can i differentiate a router between Cisco 4000 & Cisco 4000M? Also, for a 4000M, what is the max amount of flash it can handle? (I want to load at least IOS 12.1 on it). ----- Cisco Internetwork Operating System Software IOS (tm) 4000 Software (C4000-DS-M), Version 12.0(23), RELEASE SOFTWARE (fc1) Copyright (c) 1986-2002 by cisco Systems, Inc.
