I have read about BIOS interrupts, and know that they can be accessed only in 8086 real mode. My questions: Are there any other interrupts also available ? I have read about DOS interrupts, but I am confused as to if they are available in real mode also, and what is the list of DOS interrupts. Once we enter protected mode, what happens to the BIOS interrupt table stored at 0x00 ? Is it replaces, or is it present but just not accessible ? BIOS interrupts like 0x13 or 0x19, how are they implemented ? Is it in software or through the processor ?

What interrupts are available in 8086 real mode?
