How can I access a device using phisical address in win95?

I  have made  a PC card (ISA bus) composed of a dual port ram.
 
I need to read and write the ram in my app which is coded using MFC in WIN95

 I know that I can access  the ram directly  In MS-DOS. For example to write

10 at adress 0x08000 where the ram is mapped

unsigned int * a = ox08000;
(*a) = 10;

but I don't know how to do it  in WIN95 using MFC

Please, help me to solve that problem

Thank you
