DPMI 0.9+ - SET DESCRIPTOR

AX = 000Ch
BX = LDT selector
ES:(E)DI -> 8-byte buffer containing descriptor

Return:
CF clear if successful CF set on error AX = error code (DPMI 1.0+) (8021h,8022h,8025h) (see #03143)

Notes: 16-bit programs use ES:DI as pointer, 32-bit must use ES:EDI. Only modify descriptors allocated with INT 31/AX=0000h. DPMI 1.0+ automatically reloads any segment registers containing the selector being modified. Not supported by MS Windows 3.0 in Standard mode
