IDT - (Interrupt Descriptor Table)

What it does ?

It shows the processors IDT (Interrupt Descriptor Table) and if you doubleclick on a list-entry, some additional information from the registry. (NT 4 only!)

How did I do this ?

I'm using a small kernelmode driver (idt.sys) which reads the IDT via

        _asm
          {
                mov   esi,mBuffer
                sidt  [esi]
                movzx ecx,word ptr [esi]
                mov   ebx,dword ptr [esi+2]
                inc   ecx                
                mov   edi,mBuffer
                mov   dummy,ecx
                mov   esi,ebx
                shr   ecx,2  
                rep   movsd
          }


btw: The drivers source is freely available, so feel free to ask if you want it !

The program loads the driver on start and unloads it when it ends. On start the program queries the registry and builds a list with the installed devices and their allocated resources.
