I have successfully built this card:

I have also successfully compiled the EMS driver (SBEMM) following the author's instructions (attached SBEMM.EXE).
For Bill of Materials, Component Placement and Configuration please check the attached files.
Default Configuration for EMS (Port Addres 260h, Window Address E000h, Window Size 64K)
=================================================================
SW1.1: OFF
SW1.2: OFF
SW1.3: OFF
SW1.4: ON
SW1.5: ON
SW1.6: OFF
SW1.7: OFF
SW1.8: ON
SW2.1: OFF
SW2.2: OFF
SW2.3: ON
SW2.4: ON
SW2.5: ON
SW2.6: OFF
SW2.7: OFF
SW2.8: OFF
Does anybody know (or make out from the schematics) the complete DIP switch combinations
for Bank Register Port Address and Window Address Configuration?
Also, does SW2.8 really controls the Page Frame size?
Any help would be appreciated....
