Hi,

can anyone tell me how to get the 32-bit absolute physical memory
location of a variable. I need this address to sent to a PCI-card which
then on its turn dumps data in the PC's memory using the PCI fifo
capability.
Currently I found a work around using the DOS-memory location and then
copy it to the applications memory. When running DOS + cwsdpmi it works,
when running W95 it doesn't. The reason is, to my opinion, that W95
enables paging while cwsdpmi doesn't.

cheers,
       Joel
