Release notes for OSS/Free v3.8s for Linux 2.0.x
================================================

This is the latest sound driver version made available for Linux 2.0.x versions.
The driver contained in the official distribution is almost two years old and
many important ioctl() calls don't work in it. This version has been backported
from Linux 2.1.66.

Installation
------------

You will need the official Linux 2.0.x (2.0.32 recommended) sources distribution
installed in /usr/src/oss. This package is a drop in replacement of the sound
driver contained there. To install this version you should execute _ALL_ the
following steps:

cd /usr/src/linux/drivers
mv sound sound.old             (or alternatively rm -rf sound) **MANDATORY**
cd /usr/src
tar xvfz ossfree38s-linux20x.tar.gz
cd /usr/src/linux

make config (or xconfig or menuconfig)		**MANDATORY**
	(You have to re-enter/check sound config options manually during 
	 this step).

make dep					**MANDATORY**

After that follow the standard kernel configuration/installation procedure.
Sound driver spesific instructions are in linux/drivers/sound/Readme*.

Other notes
-----------

OSS/Free is a stripped down version of Open Sound System. There are many 
features which are only available in the commercial OSS/Linux driver but
not included in OSS/Free. The most important additional features of OSS/Linux
are:

- OSS/Linux supports PnP cards directly. You can use PnP cards with OSS/Free
  too but you need to use the isapnptools package to wake up the card (yes,
  some lucky guys may get their PnP cards working even without isapnptools but
  in general this will not work).
- Support for PCI cards (Ensoniq AudioPCI) is included only in OSS/Linux.
- You don't need to recompile the kernel when installing OSS/Linux.
- There is support for many additional cards in OSS/Linux that will not work
  with OSS/Free (with or without using isapnptools).
- OSS/Linux supports full duplex with SB16/32/64/AWE. This feature is not 
  included in OSS/Free.

Please report any problems to hannu@opensound.com. I can't promise personal
answer to everyone contacting me but getting response helps me in fixing the
bugs in future OSS versions.
