First you use DPMI function 6 to get the segment *linear* base address. If paging is not in effect, something like this should work: #define VIRT_TO_LINEAR(addr) ((unsigned long)(addr) + _virtual_base) unsigned long _virtual_base = 0; __dpmi_get_segment_base_address (_my_ds(), &_virtual_base); You can probably use CWSDPR0.EXE to avoid paging. --gv
