INT 31 - DPMI 1.0+ - SET MULTIPLE DESCRIPTORS

	AX = 000Fh
	CX = number of descriptors to copy
	ES:(E)DI -> descriptor buffer (see #03145)
Return: CF clear if successful
	    descriptors copied
	CF set on error
	    AX = error code (8021h,8022h,8025h) (see #03143)
	    CX = number of descriptors successfully copied
Notes:	16-bit programs use ES:DI as pointer, 32-bit must use ES:EDI
	if the function fails, the first CX descriptors are valid; the
	  remainder are not modified
	DPMI 1.0+ automatically reloads any segment registers containing a
	  selector being modified
