This is the driver for the 'DOLPHIN' drive with a 34-pin Sony
compatible interface. It also works with the Lasermate CR328A. If
you have one of those, say Y. This driver does not work for the
Optics Storage 8001 drive; use the IDE-ATAPI CD-ROM driver for that
one. Please read the file Documentation/cdrom/optcd.

If you say Y here, you should also say Y or M to "ISO 9660 CD-ROM
file system support" below, because that's the file system used on

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