	help
	   This allows device drivers to enable MSI (Message Signaled
	   Interrupts).  Message Signaled Interrupts enable a device to
	   generate an interrupt using an inbound Memory Write on its
	   PCI bus instead of asserting a device IRQ pin.

	   Use of PCI MSI interrupts can be disabled at kernel boot time
	   by using the 'pci=nomsi' option.  This disables MSI for the
	   entire system.

	   If you don't know what to do here, say Y.
