Fetching Interrupt vector table or IDT   
Hi All,

I'm working on QNX 7.0 and working on Interrupt monitoring task.

1) How to know all the IRQs in a x86 system ?
2) Is there any way to fetch Interrupt vector table or IDT ? Will the "new_intrinfo" entry in syspage give any 
information on IDT ?
3) After fetching IDT, how to check if OS has handled that interrupt ?
