+	The visorbus driver is a virtualized bus for the Unisys s-Par firmware.
+	Virtualized devices allow Linux guests on a system to share disks and
+	network cards that do not have SR-IOV support, and to be accessed using
+	the partition desktop application. The visorbus driver is required to
+	discover devices on an s-Par guest, and must be present for any other
+	s-Par guest driver to function correctly.

-	If you say Y here, you will enable the Unisys visorinput driver.
+	The Unisys s-Par visorinput driver provides a virtualized system
+	console (keyboard and mouse) that is accessible through the
+	s-Par firmware's user interface. s-Par provides video using the EFI
+	GOP protocol, so If this driver is not present, the Linux guest should
+	still boot with visible output in the partition desktop, but keyboard
+	and mouse interaction will not be available.
