That would be specific to your CPU. Enable interrupts in the interrupt
enable register, and put your interrupt handler in the appropriate vector.

You will need to throw everything that you know about Windows interrupt
handling out the door. Your boot loader is the OS at that time, so you are
single threaded and not synchronization objects.
