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.
