WS-X4013 - SUP II for CAT 4000 Board Layout

I can't find a board layout showing the Flash, DRAM and NVRAM locations of the WS-X4013 anywhere on CCO.

I tried to find more info on this but didnot get any. This product is EOL so they have taken all the docs out of the server.

The best I could come up with is this:

From the title, it looks like it applies to both the S I and the S II. However, it is evident from the diagrams that they are illustrating an S I (no uplink ports, and only a single K2 chip). It is also rather evident that they are considerably different - I have one of each in front of me now.

The good and the bad news is that there is only one removable module on each, and that must be the DRAM. In the S I it is at the back right hand side like the document, and in the S II it is at the front.

I have no idea which chip is the flash, but it is soldered in. There is, however, a socket that looks like it might be for a flash expansion. In the S I it is in position U33, towards the front on the right hand side. In the S II it is U76, and is in the right corner, just behind the reset switch. I cannot guarante that is for flash - I am only guessing.

That's the best I can do for the moment.
