    how to map system bios area into main dram in us15w?

    Green Belt

      In i945 express chipset, I can set pam0 register value to 30h to map system bios area (F0000:FFFFF) into main dram.like this

      mov eax,80000091h
      mov dx,0cF8h
      out dx,eax
      mov al,30h
      mov dx,0cFCh
      out dx,al

      but it seems there is not pam0 in us15w,how can i do????
