Accessing BIOS interrupts
I need to write a kernel driver to control a hardware watchdog timer. I am very new at kernel programming (the question probably gives that away ).
I need to know if it is possible to get access to BIOS interrupts (specifically 0x15 function 0xC3) once the kernel is in protected mode. If it is I'd appreciate being directed to any relevant doco that might show how this is done.
