In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
This option enables support for the EP-2000 parallel port IDE
protocol from DataStor. If you chose to build PARIDE support
into your kernel, you may answer Y here to build in the protocol
driver, otherwise you should answer M to build it as a loadable
module. The module will be called dstr. You must also have
a high-level driver for the type of device that you want to support.
