 			Currently this function knows 686a and 8231 chips.
 			Format: [spp|ps2|epp|ecp|ecpepp]
 
+	pata_legacy.all=	[HW,LIBATA]
+			Format: <int>
+			Set to non-zero to probe primary and secondary ISA
+			port ranges on PCI systems where no PCI PATA device
+			has been found at either range.  Disabled by default.
+
+	pata_legacy.autospeed=	[HW,LIBATA]
+			Format: <int>
+			Set to non-zero if a chip is present that snoops speed
+			changes.  Disabled by default.
+
+	pata_legacy.ht6560a=	[HW,LIBATA]
+			Format: <int>
+			Set to 1, 2, or 3 for HT 6560A on the primary channel,
+			the secondary channel, or both channels respectively.
+			Disabled by default.
+
+	pata_legacy.ht6560b=	[HW,LIBATA]
+			Format: <int>
+			Set to 1, 2, or 3 for HT 6560B on the primary channel,
+			the secondary channel, or both channels respectively.
+			Disabled by default.
+
+	pata_legacy.iordy_mask=	[HW,LIBATA]
+			Format: <int>
+			IORDY enable mask.  Set individual bits to allow IORDY
+			for the respective channel.  Bit 0 is for the first
+			legacy channel handled by this driver, bit 1 is for
+			the second channel, and so on.  The sequence will often
+			correspond to the primary legacy channel, the secondary
+			legacy channel, and so on, but the handling of a PCI
+			bus and the use of other driver options may interfere
+			with the sequence.  By default IORDY is allowed across
+			all channels.
+
+	pata_legacy.opti82c46x=	[HW,LIBATA]
+			Format: <int>
+			Set to 1, 2, or 3 for Opti 82c611A on the primary

+			Format: <int>
+			Set to 1, 2, or 3 for Opti 82c465MV on the primary
+			channel, the secondary channel, or both channels
+			respectively.  Disabled by default.
+
+	pata_legacy.pio_mask=	[HW,LIBATA]
+			Format: <int>
+			PIO mode mask for autospeed devices.  Set individual
+			bits to allow the use of the respective PIO modes.
+			Bit 0 is for mode 0, bit 1 is for mode 1, and so on.
+			All modes allowed by default.
+
+	pata_legacy.probe_all=	[HW,LIBATA]
+			Format: <int>
+			Set to non-zero to probe tertiary and further ISA
+			port ranges on PCI systems.  Disabled by default.
+
+	pata_legacy.probe_mask=	[HW,LIBATA]
+			Format: <int>
+			Probe mask for legacy ISA PATA ports.  Depending on
+			platform configuration and the use of other driver
+			options up to 6 legacy ports are supported: 0x1f0,
+			0x170, 0x1e8, 0x168, 0x1e0, 0x160, however probing
+			of individual ports can be disabled by setting the
+			corresponding bits in the mask to 1.  Bit 0 is for
+			the first port in the list above (0x1f0), and so on.
+			By default all supported ports are probed.
+
+	pata_legacy.qdi=	[HW,LIBATA]
+			Format: <int>
+			Set to non-zero to probe QDI controllers.  By default
+			set to 1 if CONFIG_PATA_QDI_MODULE, 0 otherwise.
+
+	pata_legacy.winbond=	[HW,LIBATA]
+			Format: <int>
+			Set to non-zero to probe Winbond controllers.  Use
+			the standard I/O port (0x130) if 1, otherwise the
+			value given is the I/O port to use (typically 0x1b0).
+			By default set to 1 if CONFIG_PATA_WINBOND_VLB_MODULE,
+			0 otherwise.
+
+	pata_platform.pio_mask=	[HW,LIBATA]
+			Format: <int>
+			Supported PIO mode mask.  Set individual bits to allow
+			the use of the respective PIO modes.  Bit 0 is for
+			mode 0, bit 1 is for mode 1, and so on.  Mode 0 only
+			allowed by default.
