+ 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.
