@subheading Description

Please refer to @ref{DPMI Specification} for details on DPMI
function call operation.  Also see @ref{DPMI Overview} for general
information.

DPMI function AX = 0x0205

This function installs a protected-mode interrupt (not exception)
handler.  You must pass a selector:offset pair.  Hardware interrupts
will always be reflected to protected mode if you install a handler.
You must explicitely @code{sti} before @code{iret} because @code{iret}
won't always restore interrupts in a virtual environment.

@subheading Return Value

-1 on error, else zero.
