If you noticed , he had 2/2 meg of Ram, do you think ANY Cisco IOS vers can
be compressed and still run correctly with 4 meg of Ram ....
I think some of you guys need figure out which is the DRAM , what is it's
purpose, which is the Flash and what purpose does it serve, what is the
implication of insufficient DRAM and insufficient FLASH. What's the
implication of compressing the IOS image. FYI , compressed image is not
supported for 2500 and 1600 series (except for 1600R series)
Each of the IOS has a certain requirements pertaining to Flash and DRAM,
sometimes it appears to work fine even if your router doesn't meet those
requirement, good for you. But if it breaks and you didn't meet the minimum
requirement or if you use it in a unsupported way, one of the first thing to
do make sure you meet the requirements.....
