+ This file contains notes for users of PSS sound cards who wish to use the
+newly added features of the newest version of this driver.
+
+ The major enhancements present in this new revision of this driver is the
+addition of two new module parameters that allow you to take full advantage of
+all the features present on your PSS sound card. 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.
+
+pss_firmware
+
+ This parameter can be used to specify the file containing the firmware
+code so that a user could tell the driver where that file is located instead
+of having to put it in a predefined location with a predefined name. The
+default setting of this parameter is "/etc/sound/pss_synth" as this was the
+path and filename the hardcoded value in the previous versions of this driver.
+
+Examples:
+
+# Normal PSS sound card system, loading of drivers.
+# Should be specified in an rc file (ex. Slackware uses /etc/rc.d/rc.modules).
+
+/sbin/modprobe pss pss_io=0x220 mpu_io=0x338 mpu_irq=9 mss_io=0x530 mss_irq=10 mss_dma=1 pss_cdrom_port=0x340 pss_enable_joystick=1
+/sbin/modprobe aztcd aztcd=0x340
+/sbin/modprobe joystick
+
+# System using the PSS sound card just for its CDROM and joystick ports.
+# Should be specified in an rc file (ex. Slackware uses /etc/rc.d/rc.modules).
+
+/sbin/modprobe pss pss_io=0x220 pss_cdrom_port=0x340 pss_enable_joystick=1 pss_no_sound=1
+/sbin/rmmod pss && /sbin/rmmod ad1848 && /sbin/rmmod mpu401 && /sbin/rmmod sound && /sbin/rmmod soundcore # This line not needed, but saves memory.
+/sbin/modprobe aztcd aztcd=0x340
+/sbin/modprobe joystick
