In an assembler listing of a Windows program I saw two different methods
to call an BIOS/DOS interrupt. The first was, to set up the registers
and issue INT 13H as I would do under real mode DOS even if Windows runs
in protected mode. The other was to use a DPMI service, that "simulates a
real mode interrupt".

When do I have to use which method?
