Int 31/AX=0205h

DPMI 0.9+ - SET PROTECTED MODE INTERRUPT VECTOR

AX = 0205h
BL = interrupt number
CX:(E)DX = selector:offset of handler

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

Notes: 16-bit programs use CX:DX, 32-bit programs use CX:EDX. 32-bit programs must use a 32-bit interrupt stack frame when chaining to the next handler. DPMI implementations are required to support all 256 vectors. Hardware interrupts are reflected to the virtual machine's primary client, software interrupts to the current client. Not supported by MS Windows 3.0 in Standard mode
