These features include the +ability to enable both the builtin CDROM and joystick ports. + +pss_enable_joystick + + This parameter is basically a flag. A 0 will leave the joystick port +disabled, while a non-zero value would enable the joystick port. The default +setting is pss_enable_joystick=0 as this keeps this driver fully compatible +with systems that were using previous versions of this driver. If you wish to +enable the joystick port you will have to add pss_enable_joystick=1 as an +argument to the driver. To actually use the joystick port you will then have +to load the joystick driver itself. Just remember to load the joystick driver +AFTER the pss sound driver. + +pss_cdrom_port + + This parameter takes a port address as its parameter. Any available port +address can be specified to enable the CDROM port, except for 0x0 and -1 as +these values would leave the port disabled. Like the joystick port, the cdrom +port will require that an appropriate CDROM driver be loaded before you can make +use of the newly enabled CDROM port. Like the joystick port option above, +remember to load the CDROM driver AFTER the pss sound driver. While it may +differ on some PSS sound cards, all the PSS sound cards that I have seen have a +builtin Wearnes CDROM port. If this is the case with your PSS sound card you +should load aztcd with the appropriate port option that matches the port you +assigned to the CDROM port when you loaded your pss sound driver. (ex. +modprobe pss pss_cdrom_port=0x340 && modprobe aztcd aztcd=0x340) The default +setting of this parameter leaves the CDROM port disabled to maintain full +compatibility with systems using previous versions of this driver. + + Other options have also been added for the added convenience and utility +of the user. These options are only available if this driver is loaded as a +module. + +pss_no_sound + + This module parameter is a flag that can be used to tell the driver to +just configure non-sound components. 0 configures all components, a non-0 +value will only attept to configure the CDROM and joystick ports. This +parameter can be used by a user who only wished to use the builtin joystick +and/or CDROM port(s) of his PSS sound card. If this driver is loaded with this +parameter and with the parameter below set to true then a user can safely unload +this driver with the following command "rmmod pss && rmmod ad1848 && rmmod +mpu401 && rmmod sound && rmmod soundcore" and retain the full functionality of +his CDROM and/or joystick port(s) while gaining back the memory previously used +by the sound drivers. This default setting of this parameter is 0 to retain +full behavioral compatibility with previous versions of this driver. + +pss_keep_settings + + This parameter can be used to specify whether you want the driver to reset +all emulations whenever its unloaded. This can be useful for those who are +sharing resources (io ports, IRQ's, DMA's) between different ISA cards. This +flag can also be useful in that future versions of this driver may reset all +emulations by default on the driver's unloading (as it probably should), so +specifying it now will ensure that all future versions of this driver will +continue to work as expected. The default value of this parameter is 1 to +retain full behavioral compatibility with previous versions of this driver. + +/*(DEBLOBBED)*/ + +Examples: + +# Normal PSS sound card system, loading of drivers. +# Should be specified in an rc file (ex.
