Returns addresses of the V86 mode, protected-mode, and VMM fault handlers for a specified fault. Uses Flags.

Returns with the carry flag clear if successful, set otherwise. If the carry flag is clear, the following registers contain the following values:

Register	Description
EDI	Contains the address of the handler for VMM faults. This register contains zero if no handler has been installed.
EDX	Contains the address of the handler for V86 mode faults. This register contains zero if no handler has been installed.
ESI	Contains the address of the handler for protected-mode faults. This register contains zero if no handler has been installed.

FaultNo

Fault number for which to retrieve information.

A virtual device cannot get the hook address for the Non-Maskable Interrupt (Interrupt 2). It must use the Get_NMI_Handler_Addr and Set_NMI_Handler_Addr services to hook Interrupt 2.
