The DS5000/2xx use MS02-AA (8MB) and MS02-CA (32MB).  These are relatively
large boards with a large connector on the bottom.

The DS3100/2100 uses MS01-AA (2MB each in pairs of 2).  The DS5000/xx and
DS5000/1xx can also use MS01-AA but that will limit your maximum memory to
32MB.  Using MS01-CA (8MB each in pairs of 2) you can go up 128MB.
