+
+   READ THIS
+
+   This module started to configure the Audio Excel DSP 16 Sound Card.
+   Now works with the SC-6000 (old aedsp16) and new SC-6600 based cards.
+
+   NOTE: I have NO idea about Audio Excel DSP 16 III. If someone owns this
+   audio card and want to see the kernel support for it, please contact me.
+
+   Audio Excel DSP 16 is an SB pro II, Microsoft Sound System and MPU-401
+   compatible card.
+   It is software-only configurable (no jumpers to hard-set irq/dma/mpu-irq),
+   so before this module, the only way to configure the DSP under linux was
+   boot the MS-DOS loading the sound.sys device driver (this driver soft-
+   configure the sound board hardware by massaging someone of its registers),
+   and then ctrl-alt-del to boot linux with the DSP configured by the DOS
+   driver.
+
+   This module works configuring your Audio Excel DSP 16's irq, dma and
+   mpu-401-irq. The OSS Lite routines rely on the fact that if the
+   hardware is there, they can detect it. The problem with AEDSP16 is
+   that no hardware can be found by the probe routines if the sound card
+   is not configured properly. Sometimes the kernel probe routines can find
+   an SBPRO even when the card is not configured (this is the standard setup
+   of the card), but the SBPRO emulation don't work well if the card is not
+   properly initialized. For this reason
+
+   aedsp16_init_board()
+
+   routine is called before the OSS Lite probe routines try to detect the
+   hardware.
+
+   NOTE (READ THE NOTE TOO, IT CONTAIN USEFUL INFORMATIONS)
+
+   NOTE: Now it works with SC-6000 and SC-6600 based audio cards. The new cards
+   have no jumper switch at all. No more WSS or MPU-401 I/O port switches. They
+   have to be configured by software.
+
+   NOTE: The driver is merged with the new OSS Lite sound driver. It works
+   as a lowlevel driver.
+
+   The Audio Excel DSP 16 Sound Card emulates both SBPRO and MSS;
+   the OSS Lite sound driver can be configured for SBPRO and MSS cards
+   at the same time, but the aedsp16 can't be two cards!!
+   When we configure it, we have to choose the SBPRO or the MSS emulation
+   for AEDSP16. We also can install a *REAL* card of the other type (see [1]).
+
+   NOTE: If someone can test the combination AEDSP16+MSS or AEDSP16+SBPRO
+   please let me know if it works.
+
+   The MPU-401 support can be compiled in together with one of the other
+   two operating modes.
+
+   NOTE: This is something like plug-and-play: we have only to plug
+   the AEDSP16 board in the socket, and then configure and compile
+   a kernel that uses the AEDSP16 software configuration capability.
+   No jumper setting is needed!
+
+   For example, if you want AEDSP16 to be an SBPro, on irq 10, dma 3
+   you have just to make config the OSS Lite package, configuring
+   the AEDSP16 sound card, then activating the SBPro emulation mode
+   and at last configuring IRQ and DMA.
+   Compile the kernel and run it.
+
+   NOTE: This means for SC-6000 cards that you can choose irq and dma,
+   but not the I/O addresses. To change I/O addresses you have to set
+   them with jumpers. For SC-6600 cards you have no jumpers so you have
+   to set up your full card configuration in the make config.
+
+   You can change the irq/dma/mirq settings WITHOUT THE NEED to open
+   your computer and massage the jumpers (there are no irq/dma/mirq
+   jumpers to be configured anyway, only I/O BASE values have to be
+   configured with jumpers)
+
+   For some ununderstandable reason, the card default of irq 7, dma 1,
+   don't work for me. Seems to be an IRQ or DMA conflict. Under heavy
+   HDD work, the kernel start to erupt out a lot of messages like:
+
+   'Sound: DMA timed out - IRQ/DRQ config error?'
+
+   For what I can say, I have NOT any conflict at irq 7 (under linux I'm
+   using the lp polling driver), and dma line 1 is unused as stated by
+   /proc/dma. I can suppose this is a bug of AEDSP16. I know my hardware so
+   I'm pretty sure I have not any conflict, but may be I'm wrong. Who knows!
+   Anyway a setting of irq 10, dma 3 works really fine.
+
+   NOTE: if someone can use AEDSP16 with irq 7, dma 1, please let me know
+   the emulation mode, all the installed hardware and the hardware
+   configuration (irq and dma settings of all the hardware).
+
+   This init module should work with SBPRO+MSS, when one of the two is
+   the AEDSP16 emulation and the other the real card. (see [1])
+   For example:
+
+   AEDSP16 (0x220) in SBPRO emu (0x220) + real MSS + other
+   AEDSP16 (0x220) in MSS emu + real SBPRO (0x240) + other
+
+   MPU401 should work. (see [2])

+
+   TODO, WISHES AND TECH
+
+   - About I/O ports allocation -
+
+   Request the 2x0h region (port base) in any case if we are using this card.
+
+   NOTE: the "aedsp16 (base)" string with which we are requesting the aedsp16
+   port base region (see code) does not mean necessarily that we are emulating
+   sbpro.  Even if this region is the sbpro I/O ports region, we use this
+   region to access the control registers of the card, and if emulating
+   sbpro, I/O sbpro registers too. If we are emulating MSS, the sbpro
+   registers are not used, in no way, to emulate an sbpro: they are
+   used only for configuration purposes.
+
+   Started Fri Mar 17 16:13:18 MET 1995
+
+   v0.1 (ALPHA, was an user-level program called AudioExcelDSP16.c)
+   - Initial code.
+   v0.2 (ALPHA)
+   - Cleanups.
+   - Integrated with Linux voxware v 2.90-2 kernel sound driver.
+   - SoundBlaster Pro mode configuration.
+   - Microsoft Sound System mode configuration.
+   - MPU-401 mode configuration.
+   v0.3 (ALPHA)
+   - Cleanups.
+   - Rearranged the code to let aedsp16_init_board be more general.
+   - Erased the REALLY_SLOW_IO. We don't need it. Erased the linux/io.h
+   inclusion too. We rely on os.h
+   - Used the  to get a variable
+   len string (we are not sure about the len of Copyright string).
+   This works with any SB and compatible.
+   - Added the code to request_region at device init (should go in
+   the main body of voxware).
+   v0.4 (BETA)
+   - Better configure.c patch for aedsp16 configuration (better
+   logic of inclusion of AEDSP16 support)
+   - Modified the conditional compilation to better support more than
+   one sound card of the emulated type (read the NOTES above)
+   - Moved the sb init routine from the attach to the very first
+   probe in sb_card.c
+   - Rearrangements and cleanups
+   - Wiped out some unnecessary code and variables: this is kernel
+   code so it is better save some TEXT and DATA
+   - Fixed the request_region code. We must allocate the aedsp16 (sbpro)
+   I/O ports in any case because they are used to access the DSP
+   configuration registers and we can not allow anyone to get them.
+   v0.5
+   - cleanups on comments
+   - prep for diffs against v3.0-proto-950402
+   v0.6
+   - removed the request_region()s when compiling the MODULE sound.o
+   because we are not allowed (by the actual voxware structure) to
+   release_region()
+   v0.7 (pre ALPHA, not distributed)
+   - started porting this module to kernel 1.3.84. Dummy probe/attach
+   routines.
+   v0.8 (ALPHA)
+   - attached all the init routines.
+   v0.9 (BETA)
+   - Integrated with linux-pre2.0.7
+   - Integrated with configuration scripts.
+   - Cleaned up and beautyfied the code.
+   v0.9.9 (BETA)
+   - Thanks to Piercarlo Grandi: corrected the conditonal compilation code.
+     Now only the code configured is compiled in, with some memory saving.
+   v0.9.10
+   - Integration into the sound/lowlevel/ section of the sound driver.
+   - Re-organized the code.
+   v0.9.11 (not distributed)
+   - Rewritten the init interface-routines to initialize the AEDSP16 in
+     one shot.
+   - More cosmetics.
+   - SC-6600 support.
+   - More soft/hard configuration.
+   v0.9.12
+   - Refined the v0.9.11 code with conditional compilation to distinguish
+     between SC-6000 and SC-6600 code.
+   v1.0.0
+   - Prep for merging with OSS Lite and Linux kernel 2.1.13
+   - Corrected a bug in request/check/release region calls (thanks to the
+     new kernel exception handling).
+
+   Known Problems:
+   - Audio Excel DSP 16 III don't work with this driver.
+
+   Credits:
+   Many thanks to Gerald Britton <gbritton@CapAccess.org>. He helped me a
+   lot in testing the 0.9.11 and 0.9.12 versions of this driver.
