The following message occurs when data defined in the data segment is
overridden with a Segment Override using the code segment register:

foo.OBJ(foo.ASM): error L2002: fixup overflow at 0012 in segment_TEXT
pos: 658 Record type: 73EE
frm seg _TEXT, tgt seg _DATA

This error occurs when you incorrectly try to access data in the code
segment rather than in the data segment in the following line:

        mov     word ptr cs:old_dma_vect,bx     ;

The line should be as follows:

     mov        word ptr ds:old_dma_vect,bx   ;

Code Sample:

      .DATA
old_dma_vect    dd      0
       .CODE
;
capture proc
      .
      .
      .
        mov     word ptr cs:old_dma_vect,bx     ; (INCORRECT)
     mov        word ptr ds:old_dma_vect,bx   ; (CORRECT)
      .
        end capture
