Methods to emulate a message signaled interrupt (MSI) with multiple interrupt vectors are described herein. An embodiment of the invention includes a memory decoder to monitor a predetermined memory location allocated to a device and to generate an emulated message signaled interrupt (MSI) signal in response to a posted write transaction to the predetermined memory location initiated from the device, and an interrupt controller, in response to the emulated MSI signal from the memory decoder, to invoke processing of a plurality of interrupts based on a plurality of interrupt vectors retrieved from the predetermined memory location, without receiving an actual MSI interrupt request from the device.
