"Show Memory" total does not equal total installed memory

Why doesn't the Total I/O memory and Processor memory totals displayed while using "Show Memeory" equal the installed memory displayed when using "Show version?"

I have always been aware of a slight difference between the two numbers but my 3845 seem to me missing over 70 megs!

The memory used by the IOS does not show up in the output of "show memory"

Re: "Show Memory" total does not equal total installed memory

My 7206VXR has a 21 meg IOS image yet only 14 meg is missing between my "show ver" and "show mem" yet my 3845 has a 24 meg IOS image but 70 megs is missing between the two commands. Does the 7206 only load part of the image and the 3845 loads the whole image? If so, is there any document available that explains how each units loads the image?
