                mov ESI, aptr;
                mov EDI, bptr;
                mov CL, value;

                align 4;
            startadd386:
                add ESI, 4;
                mov DX, [EDI];
                mov AX, [EDI+2];
                add EDI, 4;
                add AL, CL;
                add AH, CL;
                add DL, CL;
                add DH, CL;
                mov [ESI   -4], DX;
                mov [ESI+2 -4], AX;
                cmp ESI, n;
                jb startadd386;

                mov aptr, ESI;
                mov bptr, EDI;

though the function looks buggy.
