You're wrong - that's an undocumented feature.
I have a couple of old 2500 boxes with small flash (mostly 4M) that
runing new compressed images without any problems.
The only problem can be if you have _really_ old box with prehistoric
loader code.
At the load time if loader see the *.Z image on the flash - it loads and
decompresses
it to RAM. Like the situation where you run from TFTP server.
Be warned - you'll need at least 16M of RAM.
The second drawback - 2500 has two memory bus architecture - one for FLASH
(usually for
IOS ode) and second for RAM - usually the packet buffer space.
Whan you run IOS from RAM, in principle, you loose some performance.
Try yourself and don't always trust the docs. :-)
Regards,
Eugene

Not on a 2500 (which runs the IOS from flash) unfortunately!!

If you have enough RAM installed - you can compress the image with Unix
'compress' and
then it'll fit into 8M flash.
The drawback is that it'll run from RAM and the boot time will be looooong.

Eugene
