The switches are to set starting adress of addon ram.

It seems the card can fill up XMS Memory, and also supports EMS
so chances are there that you can set both EMS Memory and XMS Memory with each of the DIP Switches.
So you have both types of Memory.

You may want to try the DIP Switch settings on the Photo.
As the Seller states he tested the Card with 4x256Kb RAM on it.
For XMS no driver is needed, the BIOS should simply count it up.
EDIT:
Are you the Seller of this Card ? (identical pictures)
