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.
