The manual i have is for the series 2, on this one you dont specify the amount of ram, you just tell it if its using any combination involving a 16mb simm.
So it has a jumper > jp3, that is installed if using a single 1 or 4mb simms. the jumper is removed if using a 16mb in either socket even if there is a 1 or 4 in the other.
Maybe this will help you a bit?
