-			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.
