Help text

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.
