If you say Y here, your kernel will be able to manage ATA/(E)IDE and
ATAPI units. The most common cases are IDE hard drives and ATAPI
CD-ROM drives.

This subsystem is currently in maintenance mode with only bug fix
changes applied. Users of ATA hardware are encouraged to migrate to
the newer ATA subsystem ("Serial ATA (prod) and Parallel ATA
(experimental) drivers") which is more actively maintained.

To compile this driver as a module, choose M here: the
module will be called ide-core.

For further information, please read <file:Documentation/ide/ide.txt>.

If unsure, say N.
