This image is only 8MB,why it requires 32MB Flash since basically Flash is used to store IOS image?
Is it true that generally I can copy an image to a Flash a little bit larger than the image?As long as I can copy it to flash,I can run it,right?
In flash requirement,I never see sizes like 24MB.Is it because the Flash requirement only has 8,16,32 and so on and those irregular sizes are not considered but I can still run a image smaller than my Flash.For example,run this image with 8MB+4MB SIMM Flash.
Flash size is recommended more than image size due to the fact that it stores vlan information and some time in many cases sdm info and GUI helper files so that we can access that perticular device through IE.
We can use the following command to push in image bigger than the flash.
To permanently erase files tagged as "deleted" or "error" on Class A Flash file systems, use the squeeze command in EXEC mode.
squeeze [/nolog] [/quiet] filesystem:

Hope this helps your queries.
