Hi,

Correct.  Some of them have 2Mb soldered on-board, though, so a 4 Mb
2500 could have 2+2 or 0+4, IIRC...

Now that's really cool news :-)

For the 36xx series with not-so-current IOS versions, there is another 
way to find out the memory layout - going through IOS memory, finding 
the location where the boot ROM stores the memory layout and then 
looking there for the information:

Most of the NPEs take only one SIMM anyway (NPE-225, NPE-400, NPE-G1),
so on the 7206VXR, this feature won't be as helpful as for the others...

But nevertheless: thanks for implementing such useful stuff!
