Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+Pro Audio Spectrum 16 for 2.3.99 and later
+by Thomas Molina (tmolina@home.com)
+last modified 3 Mar 2001
+Acknowledgement to Axel Boldt (boldt@math.ucsb.edu) for stuff taken
+from Configure.help, Riccardo Facchetti for stuff from README.OSS,
+and others whose names I could not find.
+This documentation is relevant for the PAS16 driver (pas2_card.c and
+friends) under kernel version 2.3.99 and later. If you are
+unfamiliar with configuring sound under Linux, please read the
+Sound-HOWTO, Documentation/sound/oss/Introduction and other
+relevant docs first.
+The following information is relevant information from README.OSS
+and legacy docs for the Pro Audio Spectrum 16 (PAS16):
+The pas2_card.c driver supports the following cards --
+Pro Audio Spectrum 16 (PAS16) and compatibles:
+ Pro Audio Spectrum 16
+ Pro Audio Studio 16
+ Logitech Sound Man 16
+ NOTE! The original Pro Audio Spectrum as well as the PAS+ are not
+ and will not be supported by the driver.
+The sound driver configuration dialog
+Sound configuration starts by making some yes/no questions. Be careful
+when answering to these questions since answering y to a question may
+prevent some later ones from being asked. For example don't answer y to
+the question about (PAS16) if you don't really have a PAS16. Sound
+configuration may also be made modular by answering m to configuration
+options presented.
+Note also that all questions may not be asked. The configuration program
+may disable some questions depending on the earlier choices. It may also
+select some options automatically as well.
+ "ProAudioSpectrum 16 support",
+ - Answer 'y'_ONLY_ if you have a Pro Audio Spectrum _16_,
+ Pro Audio Studio 16 or Logitech SoundMan 16 (be sure that
+ you read the above list correctly). Don't answer 'y' if you
+ have some other card made by Media Vision or Logitech since they
+ are not PAS16 compatible.
+ NOTE! Since 3.5-beta10 you need to enable SB support (next question)
+ if you want to use the SB emulation of PAS16. It's also possible to
+ the emulation if you want to use a true SB card together with PAS16
+ (there is another question about this that is asked later).
+ "Generic OPL2/OPL3 FM synthesizer support",
+ - Answer 'y' if your card has a FM chip made by Yamaha (OPL2/OPL3/OPL4).
+ The PAS16 has an OPL3-compatible FM chip.
+With PAS16 you can use two audio device files at the same time. /dev/dsp (and
+/dev/audio) is connected to the 8/16 bit native codec and the /dev/dsp1 (and
+/dev/audio1) is connected to the SB emulation (8 bit mono only).
+The new stuff for 2.3.99 and later
+The following configuration options from Documentation/Configure.help
+are relevant to configuring the PAS16:
+Sound card support
+ If you have a sound card in your computer, i.e. if it can say more
+ than an occasional beep, say Y. Be sure to have all the information
+ about your sound card and its configuration down (I/O port,
+ interrupt and DMA channel), because you will be asked for it.
+ You want to read the Sound-HOWTO, available from
+ http://www.tldp.org/docs.html#howto . General information
+ about the modular sound system is contained in the files
+ Documentation/sound/oss/Introduction. The file
+ Documentation/sound/oss/README.OSS contains some slightly outdated but
+ still useful information as well.
+OSS sound modules
+ OSS is the Open Sound System suite of sound card drivers. They make
+ sound programming easier since they provide a common API. Say Y or M
+ here (the module will be called sound.o) if you haven't found a
+ driver for your sound card above, then pick your driver from the
+ list below.
+Persistent DMA buffers
+ Linux can often have problems allocating DMA buffers for ISA sound
+ cards on machines with more than 16MB of RAM. This is because ISA
+ DMA buffers must exist below the 16MB boundary and it is quite
+ possible that a large enough free block in this region cannot be
+ found after the machine has been running for a while. If you say Y
+ here the DMA buffers (64Kb) will be allocated at boot time and kept
+ until the shutdown. This option is only useful if you said Y to
+ "OSS sound modules", above. If you said M to "OSS sound modules"
+ then you can get the persistent DMA buffer functionality by passing
+ the command-line argument "dmabuf=1" to the sound.o module.
+ Say y here for PAS16.
+ProAudioSpectrum 16 support
+ Answer Y only if you have a Pro Audio Spectrum 16, ProAudio Studio
+ 16 or Logitech SoundMan 16 sound card. Don't answer Y if you have
+ some other card made by Media Vision or Logitech since they are not
+ PAS16 compatible. It is not necessary to enable the separate
+ Sound Blaster support; it is included in the PAS driver.
+ If you compile the driver into the kernel, you have to add
+ "pas2=<io>,<irq>,<dma>,<dma2>,<sbio>,<sbirq>,<sbdma>,<sbdma2>
+ to the kernel command line.
+FM Synthesizer (YM3812/OPL-3) support
+ Answer Y if your card has a FM chip made by Yamaha (OPL2/OPL3/OPL4).
+ Answering Y is usually a safe and recommended choice, however some
+ cards may have software (TSR) FM emulation. Enabling FM support with
+ these cards may cause trouble (I don't currently know of any such
+ cards, however).
+ Please read the file Documentation/sound/oss/OPL3 if your card has an
+ OPL3 chip.
+ If you compile the driver into the kernel, you have to add
+ "opl3=<io>" to the kernel command line.
+ If you compile your drivers into the kernel, you MUST configure
+ OPL3 support as a module for PAS16 support to work properly.
+ You can then get OPL3 functionality by issuing the command:
+ insmod opl3
+ In addition, you must either add the following line to
+ /etc/modprobe.conf:
+ options opl3 io=0x388
+ or else add the following line to /etc/lilo.conf:
+ opl3=0x388
+To use the PAS16 in my computer I have enabled the following sound
+configuration options:
+I have also included the following append line in /etc/lilo.conf:
+append="pas2=0x388,10,3,-1,0x220,5,1,-1 sb=0x220,5,1,-1 opl3=0x388"
+The io address of 0x388 is default configuration on the PAS16. The
+irq of 10 and dma of 3 may not match your installation. The above
+configuration enables PAS16, 8-bit Soundblaster and OPL3
+functionality. If Soundblaster functionality is not desired, the
+following line would be appropriate:
+append="pas2=0x388,10,3,-1,0,-1,-1,-1 opl3=0x388"
+If sound is built totally modular, the above options may be
+specified in /etc/modprobe.conf for pas2, sb and opl3
