Int 31 Fn 0007  P - Dpmi 0.9+ - Set Segment Base Address                   [E]

   AX = 0007h
   BX = selector
   CX:DX = linear base address

Return: CF clear if successful
   CF set on error
       AX = error code (DPMI 1.0+) (8022h,8025h) (see #2814)

Notes: only modify descriptors allocated with INT 31/AX=0000h
   only the low 24 bits of the address will be used by 16-bit DPMI
     implementations even on a 386 or higher
   DPMI 1.0+ automatically reloads any segment registers containing the
     selector being modified
   not supported by MS Windows 3.0 in Standard mode
