- 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?
