Added code to allow a user + * to only use this driver for enabling non-sound components + * through the new module parameter pss_no_sound (flag). Added + * code that would allow a user to decide whether the driver should + * reset the configured hardware settings for the PSS board through + * the module parameter pss_keep_settings (flag). This flag will + * allow a user to free up resources in use by this card if needbe, + * furthermore it allows him to use this driver to just enable the + * emulations and then be unloaded as it is no longer needed. Both + * new settings are only available to this driver if compiled as a + * module. The default settings of all new parameters are set to + * load the driver as it did in previous versions. + * 04-07-1999: Anthony Barbachan <barbcode@xmen.cis.fordham.edu> + * Added module parameter pss_firmware to allow the user to tell + * the driver where the fireware file is located.
