I need to change an entry in the IVT (Interupt vector table) to point to my handler instead of pointing to the operating system habdler.
I know the IVT starts at address 0 but i cant reach this address, only if i will run in kernel mode.

how do i write this code?
Thanks ahead.

Depends on the OS that you are running. In Windows, write a driver. In *nix, write a kernel module.
