+	  This is the generic IDE driver.  This driver attaches to the
+	  fixed legacy ports (e.g. on PCs 0x1f0/0x170, 0x1e8/0x168 and
+	  so on).  Please note that if this driver is built into the
+	  kernel or loaded before other ATA (IDE or libata) drivers
+	  and the controller is located at legacy ports, this driver
+	  may grab those ports and thus can prevent the controller
+	  specific driver from attaching.
+
+	  Also, currently, IDE generic doesn't allow IRQ sharing
+	  meaning that the IRQs it grabs won't be available to other
+	  controllers sharing those IRQs which usually makes drivers
+	  for those controllers fail.  Generally, it's not a good idea
+	  to load IDE generic driver on modern systems.
+
 	  If unsure, say N.
