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

I designed the pc- card use the address lines a0-a19 in ISA

If you change to using IO mapping, access to your dual port RAM is much simpler under '95.  Also, it is quite antisocial to reserve chunks of ISA high memory.
