Abstract
A method of increasing the quantity of input/output (I/O) decode ranges using system management interrupts (SMI) traps is disclosed. In one aspect, the present disclosure teaches a method of increasing the quantity of I/O decode ranges using SMI traps in a chipset including generating a system management interrupt (SMI) based on information causing access to an I/O address that triggers a SMI trap. The I/O address operably received at the chipset via a bus.
