I did. Stuck in moderation. Correct, int 13h.

  Wasn’t 13h disk services? Guess they got shared? Or is it hardware interrupt 13h mapped somewhere else through the interrupt controller?

    Should be int 16h I think.

      Int 16h was the BIOS keyboard services.

        Right, thanks.

    It was actually IRQ13 -- one of the input pins on the slave interrupt controller. It was typically mapped to INT 75h. I don't know if Windows remapped it.
