I've found that the limit is about a 12.5 meg uncompressed IOS image when
the router has 16 meg DRAM. Anything above that caused problems loading and
running.

Key Point - MZMAKER images run from RAM, so you'll have to have enough
memory for the
1. image to uncompress into RAM
2. router to operate in the remaining RAM
Case in point to share: I tried a 13M compressed image (12.1 IP/IPX/AT/DEC
Plus) on a 8/16 router (no shared memory soldered on the board, so really
8/14/2). When it uncompressed, there was not enough RAM to boot the image,
so I had to back down to the next smaller compressed image (12.1
IP/IPX/AT/DEC).
good luck!
