hi. is there a method to find out how irqs are mapped to "normal" interrupts? for example the keyboard uses irq1 and irq1 is "normally" mapped to int 09h. but windows maps irq1 to int 51h. so what will i have to do to find out how they are mapped on any system? will i have to write some special values to port 20h or 21h (those ports are used by the PIC)? Any ideas?
