2.21 - DPMI function 0204h - Get Protected Mode Interrupt Vector

Returns the address of the current protected mode interrupt handler for the specified interrupt.


In: AX = 0204h
BL = interrupt number
Out: CF clear
CX:EDX = selector:offset of exception handler


a) The value returned in CX is a valid protected mode selector, not a real mode segment address.

b) Client should use DPMI function 0202h to obtain addresses of exception handlers, since interrupt and exception handler's addresses may be different for interrupts in range INT 00-0Fh.
