What do you mean by normal memory address?  If you mean "char *", then
yes, you can.  The segment is _go32_my_cs, and the offset is (int)ptr.
I don't think this will do you much good though - I think you're
talking about something you can use in real mode.  Sorry, real mode
programs won't be able to see the 32-bit memory anyway.

You can convert a linear address in the dos memory by using divide and
remainder functions.  This is useful for the linear addresses in
_go32_info_block.
