It contain useful +information. + +Configuration +------------- + +The Audio Excel configuration, is now done with the standard Linux setup. +You have to configure the sound card (Sound Blaster or Microsoft Sound System) +and, if you want it, the Roland MPU-401 (do not use the Sound Blaster MPU-401, +SB-MPU401) in the main driver menu. Activate the lowlevel drivers then select +the Audio Excel hardware that you want to initialize. Check the IRQ/DMA/MIRQ +of the Audio Excel initialization: it must be the same as the SBPRO (or MSS) +setup. If the parameters are different, correct it. +I you own a Gallant's audio card based on SC-6600, activate the SC-6600 support. +If you want to change the configuration of the sound board, be sure to +check off all the configuration items before re-configure it. + +Module parameters +----------------- +To use this driver as a module, you must configure some module parameters, to +set up I/O addresses, IRQ lines and DMA channels. Some parameters are +mandatory while some others are optional. Here a list of parameters you can +use with this module: + +Name Description +==== =========== +MANDATORY +io I/O base address (0x220 or 0x240) +irq irq line (5, 7, 9, 10 or 11) +dma dma channel (0, 1 or 3) + +OPTIONAL +mss_base I/O base address for activate MSS mode (default SBPRO) + (0x530 or 0xE80) +mpu_base I/O base address for activate MPU-401 mode + (0x300, 0x310, 0x320 or 0x330) +mpu_irq MPU-401 irq line (5, 7, 9, 10 or 0) + +A configuration file in /etc/modprobe.d/ directory will have lines like this: + +options opl3 io=0x388 +options ad1848 io=0x530 irq=11 dma=3 +options aedsp16 io=0x220 irq=11 dma=3 mss_base=0x530 + +Where the aedsp16 options are the options for this driver while opl3 and +ad1848 are the corresponding options for the MSS and OPL3 modules. + +Loading MSS and OPL3 needs to pre load the aedsp16 module to set up correctly +the sound card. Installation dependencies must be written in configuration +files under /etc/modprobe.d/ directory: + +softdep ad1848 pre: aedsp16 +softdep opl3 pre: aedsp16 + +Then you must load the sound modules stack in this order: +sound -> aedsp16 -> [ ad1848, opl3 ] + +With the above configuration, loading ad1848 or opl3 modules, will +automatically load all the sound stack. + +Sound cards supported +--------------------- +This driver supports the SC-6000 and SC-6600 based Gallant's sound card. +It don't support the Audio Excel DSP 16 III (try the SC-6600 code). +I'm working on the III version of the card: if someone have useful +information about it, please let me know. +For all the non-supported audio cards, you have to boot MS-DOS (or WIN95) +activating the audio card with the MS-DOS device driver, then you have to +<ctrl>-<alt>-<del> and boot Linux. +Follow these steps: + +1) Compile Linux kernel with standard sound driver, using the emulation + you want, with the parameters of your audio card, + e.g. Microsoft Sound System irq10 dma3 +2) Install your new kernel as the default boot kernel. +3) Boot MS-DOS and configure the audio card with the boot time device + driver, for MSS irq10 dma3 in our example. +4) <ctrl>-<alt>-<del> and boot Linux. This will maintain the DOS configuration + and will boot the new kernel with sound driver. The sound driver will find + the audio card and will recognize and attach it. + +Reports on User successes +------------------------- + +> Date: Mon, 29 Jul 1996 08:35:40 +0100 +> From: Mr S J Greenaway <sjg95@unixfe.rl.ac.uk> +> To: riccardo@cdc8g5.cdc.polimi.it (Riccardo Facchetti) +> Subject: Re: Audio Excel DSP 16 initialization code +> +> Just to let you know got my Audio Excel (emulating a MSS) working +> with my original SB16, thanks for the driver! + + +Last revised: 20 August 1998 +Riccardo Facchetti +fizban@tin.it |
