IBM ThinkPad 600X Laptops:
-------------------------
- You must disable APM in the BIOS. Use 'ps2 pcibusp disable', using
the Windows binary, ps2 supplied by IBM in the C:\thinkpad directory

- If you have a pcmcia network card in the machine, you may not need to
use the 'ps2 pcibusp disable' command in windows to setup the bios.
Quite a few PCMCIA cards will keep the bus in non-power-saving-state so
the sound river will work without tampering with the BIOS settings.
If you do not set the option to disable or have a network card that
keeps the bus active, you will get AC'97 read timeout error messages.


TB SantaCruz/Video Logic Sonic Fury cards:
------------------------------------------
1) There is no support for S/PDIF in/out
2) There is no support for 4 channel audio

Playing Quake
-------------
If you want to play Quake on the CS4280 drivers, you must type:
rm /dev/dsp; ln -s /dev/dsp1 /dev/dsp
This is because the default audio device /dev/dsp0 uses the 4Front SRC for
recording and mmap() is not supported with devices that use the 4Front SRC.
Linking the default /dev/dsp to /dev/dsp1 allows Quake to play normally.
