ABSTRACT:
A method for simulating an interrupt based application programming interface in a computer system, wherein a trap driver hooks to a real mode interrupt chain comprising at least one interrupt service routine for execution in a real mode of a central processing unit. The trap driver waits for a simulated real mode interrupt, and executes an interface function in a protected mode of the central processing unit if the simulated real mode interrupt specifies the application programming interface. Otherwise, the trap driver chains the simulated real mode interrupt to a next interrupt service routine in the real mode interrupt chain.
