1 | Driver | ||
2 | ------ | ||
3 | |||
4 | Informations about Audio Excel DSP 16 driver can be found in the source | ||
5 | file aedsp16.c | ||
6 | Please, read the head of the source before using it. It contain useful | ||
7 | informations. | ||
8 | |||
9 | Configuration | ||
10 | ------------- | ||
11 | |||
12 | The Audio Excel configuration, is now done with the standard Linux setup. | ||
13 | You have to configure the sound card (Sound Blaster or Microsoft Sound System) | ||
14 | and, if you want it, the Roland MPU-401 (do not use the Sound Blaster MPU-401, | ||
15 | SB-MPU401) in the main driver menu. Activate the lowlevel drivers then select | ||
16 | the Audio Excel hardware that you want to initialize. Check the IRQ/DMA/MIRQ | ||
17 | of the Audio Excel initialization: it must be the same as the SBPRO (or MSS) | ||
18 | setup. If the parameters are different, correct it. | ||
19 | I you own a Gallant's audio card based on SC-6600, activate the SC-6600 support. | ||
20 | If you want to change the configuration of the sound board, be sure to | ||
21 | check off all the configuration items before re-configure it. | ||
22 | |||
23 | Module parameters | ||
24 | ----------------- | ||
25 | To use this driver as a module, you must configure some module parameters, to | ||
26 | set up I/O addresses, IRQ lines and DMA channels. Some parameters are | ||
27 | mandatory while some others are optional. Here a list of parameters you can | ||
28 | use with this module: | ||
29 | |||
30 | Name Description | ||
31 | ==== =========== | ||
32 | MANDATORY | ||
33 | io I/O base address (0x220 or 0x240) | ||
34 | irq irq line (5, 7, 9, 10 or 11) | ||
35 | dma dma channel (0, 1 or 3) | ||
36 | |||
37 | OPTIONAL | ||
38 | mss_base I/O base address for activate MSS mode (default SBPRO) | ||
39 | (0x530 or 0xE80) | ||
40 | mpu_base I/O base address for activate MPU-401 mode | ||
41 | (0x300, 0x310, 0x320 or 0x330) | ||
42 | mpu_irq MPU-401 irq line (5, 7, 9, 10 or 0) | ||
43 | |||
44 | The /etc/modprobe.conf will have lines like this: | ||
45 | |||
46 | options opl3 io=0x388 | ||
47 | options ad1848 io=0x530 irq=11 dma=3 | ||
48 | options aedsp16 io=0x220 irq=11 dma=3 mss_base=0x530 | ||
49 | |||
50 | Where the aedsp16 options are the options for this driver while opl3 and | ||
51 | ad1848 are the corresponding options for the MSS and OPL3 modules. | ||
52 | |||
53 | Loading MSS and OPL3 needs to pre load the aedsp16 module to set up correctly | ||
54 | the sound card. Installation dependencies must be written in the modprobe.conf | ||
55 | file: | ||
56 | |||
57 | install ad1848 /sbin/modprobe aedsp16 && /sbin/modprobe -i ad1848 | ||
58 | install opl3 /sbin/modprobe aedsp16 && /sbin/modprobe -i opl3 | ||
59 | |||
60 | Then you must load the sound modules stack in this order: | ||
61 | sound -> aedsp16 -> [ ad1848, opl3 ] | ||
62 | |||
63 | With the above configuration, loading ad1848 or opl3 modules, will | ||
64 | automatically load all the sound stack. | ||
65 | |||
66 | Sound cards supported | ||
67 | --------------------- | ||
68 | This driver supports the SC-6000 and SC-6600 based Gallant's sound card. | ||
69 | It don't support the Audio Excel DSP 16 III (try the SC-6600 code). | ||
70 | I'm working on the III version of the card: if someone have useful | ||
71 | informations about it, please let me know. | ||
72 | For all the non-supported audio cards, you have to boot MS-DOS (or WIN95) | ||
73 | activating the audio card with the MS-DOS device driver, then you have to | ||
74 | <ctrl>-<alt>-<del> and boot Linux. | ||
75 | Follow these steps: | ||
76 | |||
77 | 1) 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 | ||
80 | 2) Install your new kernel as the default boot kernel. | ||
81 | 3) Boot MS-DOS and configure the audio card with the boot time device | ||
82 | driver, for MSS irq10 dma3 in our example. | ||
83 | 4) <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. | ||
86 | |||
