INT 62 u - FGDRIVER v4.02 - "FG_PUTBLOCK" - RESTORE RECTANGLE OF DISPLAY
	AX = 0098h
	ES:BX -> buffer containing previously-saved image
	CX = left edge
	DX = right edge
	SI = top edge
	DI = bottom edge
Notes:	the FGDRIVER functions are rearranged with each major release, but
	  their parameters do not change (see #03474 at AX=0000h)
	In text modes, coordinates are character positions; in graphics modes,
	  they are defined in screen space, and the left and right edges are
	  adjusted to a byte boundary if necessary
