These are sound cards with built-in cdrom interfaces using the OPTi
82C928 or 82C929 chips. Say Y here to have them detected and
possibly configured at boot time. In addition, You'll have to say Y
to a driver for the particular cdrom drive you have attached to the
card. Read Documentation/cdrom/isp16 for details.

To compile this driver as a module, choose M here: the
module will be called isp16.
