Int 31 Fn 000F  P - DPMI 1.0+ - Set Multiple Descriptors                   [E]

   AX = 000Fh
   CX = number of descriptors to copy
   ES:(E)DI -> descriptor buffer (see below)

Return: CF clear if successful
       descriptors copied
   CF set on error
       AX = error code (8021h,8022h,8025h) (see AX=0000h)
       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
