O.K., I tried using __djgpp_map_physical_memory and it isn't working for me.
I am still trying to map in physical memory from a PCI device so that I can
grant user level acess to it. I checked info for this function and this is
what I find:

int __djgpp_map_physical_memory(void *our_addr, unsigned long num_bytes,
unsigned long phys_addr);

The PCI card that I am trying to map has 8 megs of RAM and it located at
0x41000000. So I have tried doing the following:

__djgpp_map_physical_memory ( 0x800000, 41000000);

I know that this is missing the *our_addr argument, but I have tried placing
different values here without any luck (can someone please tell me what the
'our_addr parameter is for (pleaseeeeeeee)). Are there one or more other
functions that I have to call to set up page tables??...can anyone
help....huge thanks in advance.
