+          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.
