Hi:
     I remember the IRQs except clock are disabled in pure EFI environment.
     If you want to write a driver based on a legacy option ROM, and want to open some IRQ, you could check the 8259InterruptDxe driver.
     Thanks.

Hi,
Using EFI application I want to read IRQ location and values of all controllers connected to my server.  Could any one please let me know where from where can I read these IRQs from EFI application.

eg:
IRQ location
8042 Keyboard/Mouse Controller IC : 0x060
Parallel printer 1 (LPT1)         : 0x378
and
8042 Keyboard/mouse controller IC IRQ content : 0xF000E000

Thank you,
