How to patch IDT?

0 Likes

Problem:

I am trying to patch the Interrupt Descriptor Table (IDT) with an NMI handler.  Our hardware is capable of causing an NMI to be generated when the power switch is pressed. Where can I get more information on how to do that?

Resolution:

There is a very good article on how to hook interrupts. It gives an example of hooking interrupt 2D. Hyperlink: http://www.wdj.com/archive/1102/feature.html.
