-	   This replaces the current existing IRQ-based index interrupt scheme
-	   with the vector-base index scheme. The advantages of vector base
-	   over IRQ base are listed below:
-	   1) Support MSI implementation.
-	   2) Support future IOxAPIC hotplug
-
-	   Note that this allows the device drivers to enable MSI, Message
-	   Signaled Interrupt, on all MSI capable device functions detected.
-	   Message Signal Interrupt enables an MSI-capable hardware device to
-	   send an inbound Memory Write on its PCI bus instead of asserting
-	   IRQ signal on device IRQ pin.
+	   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.
 
 	   If you don't know what to do here, say N.
