   Here goes:  (This isn't the same code... I just rewrote it and
   tested it with MS Quick C 2.0 )
   (I used 2-byte moves instead of 1-byte moves when possible to speed
    things up a bit)


#include <conio.h>

char buffer[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
				  1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
				  1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
				  1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
				  1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };

void PutBlock( int x, int y, int height, int width, char far * buffer )
{   _asm {
	push    di
	push    si
	push    es
	push    ds
	mov     ax, 320
	mul     y       ; AX = y * 320
	add     ax, x   ;             + x
	mov     di, ax  ; ES:DI = destination of pixels
	mov     ax, 0A000h
	mov     es, ax  ; Segment of VGA memory
	mov     dx, height
	mov     bx, width
	mov     ax, 320
	sub     ax, bx
	lds     si, buffer

rowloop:
	mov     cx, bx  ; width of row
	shr     cx, 1   ; number of words
	rep     movsw   ; copy as many words as possible
	adc     cx, cx  ; move the odd byte
	rep     movsb
	add     di, ax  ; Go to next pixel row
	dec     dx      ;
	jnz     rowloop
	; Done
	pop     ds
	pop     es
	pop     si
	pop     di
	}
}



main()
{   int i;

	_asm {
		mov ax, 13H
		int 10h
	}

	getch();
	for (i=0; i<50; i++ )  {
		PutBlock( 10, 80+i    , 5, 10, buffer );
		getch();
	}

	_asm {
		mov ax, 03H
		int 10h
	}
	return 0;
}
