	ide-generic.probe-mask= [HW] (E)IDE subsystem

			Format: <int>

			Probe mask for legacy ISA IDE ports.  Depending on

			platform up to 6 ports are supported, enabled by

			setting corresponding bits in the mask to 1.  The

			default value is 0x0, which has a special meaning.

			On systems that have PCI, it triggers scanning the

			PCI bus for the first and the second port, which

			are then probed.  On systems without PCI the value

			of 0x0 enables probing the two first ports as if it

			was 0x3.



	ide-pci-generic.all-generic-ide [HW] (E)IDE subsystem

			Claim all unknown PCI IDE storage controllers.
