  4Informations about Audio Excel DSP 16 driver can be found in the source
  5file aedsp16.c
  6Please, read the head of the source before using it. It contain useful
  7informations.

  9Configuration
 10-------------
 11
 12The Audio Excel configuration, is now done with the standard Linux setup.
 13You have to configure the sound card (Sound Blaster or Microsoft Sound System)
 14and, if you want it, the Roland MPU-401 (do not use the Sound Blaster MPU-401,
 15SB-MPU401) in the main driver menu. Activate the lowlevel drivers then select
 16the Audio Excel hardware that you want to initialize. Check the IRQ/DMA/MIRQ
 17of the Audio Excel initialization: it must be the same as the SBPRO (or MSS)
 18setup. If the parameters are different, correct it.
 19I you own a Gallant's audio card based on SC-6600, activate the SC-6600 support.
 20If you want to change the configuration of the sound board, be sure to
 21check off all the configuration items before re-configure it.

 23Module parameters
 24-----------------
 25To use this driver as a module, you must configure some module parameters, to
 26set up I/O addresses, IRQ lines and DMA channels. Some parameters are
 27mandatory while some others are optional. Here a list of parameters you can
 28use with this module:
 29
 30Name		Description
 31====		===========
 32MANDATORY
 33io		I/O base address (0x220 or 0x240)
 34irq		irq line (5, 7, 9, 10 or 11)
 35dma		dma channel (0, 1 or 3)
 36
 37OPTIONAL
 38mss_base	I/O base address for activate MSS mode (default SBPRO)
 39		(0x530 or 0xE80)
 40mpu_base	I/O base address for activate MPU-401 mode
 41		(0x300, 0x310, 0x320 or 0x330)
 42mpu_irq		MPU-401 irq line (5, 7, 9, 10 or 0)
 43
 44The /etc/modprobe.conf will have lines like this:
 45
 46options opl3 io=0x388
 47options ad1848 io=0x530 irq=11 dma=3
 48options aedsp16 io=0x220 irq=11 dma=3 mss_base=0x530
 49
 50Where the aedsp16 options are the options for this driver while opl3 and
 51ad1848 are the corresponding options for the MSS and OPL3 modules.
 52
 53Loading MSS and OPL3 needs to pre load the aedsp16 module to set up correctly
 54the sound card. Installation dependencies must be written in the modprobe.conf
 55file:
 56
 57install ad1848 /sbin/modprobe aedsp16 && /sbin/modprobe -i ad1848
 58install opl3 /sbin/modprobe aedsp16 && /sbin/modprobe -i opl3
 59
 60Then you must load the sound modules stack in this order:
 61sound -> aedsp16 -> [ ad1848, opl3 ]
 62
 63With the above configuration, loading ad1848 or opl3 modules, will
 64automatically load all the sound stack.
 65
 66Sound cards supported
 67---------------------
 68This driver supports the SC-6000 and SC-6600 based Gallant's sound card.
 69It don't support the Audio Excel DSP 16 III (try the SC-6600 code).
 70I'm working on the III version of the card: if someone have useful
 71informations about it, please let me know.
 72For all the non-supported audio cards, you have to boot MS-DOS (or WIN95)
 73activating the audio card with the MS-DOS device driver, then you have to
 74<ctrl>-<alt>-<del> and boot Linux.
 75Follow these steps:
 76
 771) Compile Linux kernel with standard sound driver, using the emulation
 78   you want, with the parameters of your audio card,
 79   e.g. Microsoft Sound System irq10 dma3
 802) Install your new kernel as the default boot kernel.
 813) Boot MS-DOS and configure the audio card with the boot time device
 82   driver, for MSS irq10 dma3 in our example.
 834) <ctrl>-<alt>-<del> and boot Linux. This will maintain the DOS configuration
 84   and will boot the new kernel with sound driver. The sound driver will find
 85   the audio card and will recognize and attach it.
