Motorola PowerStack PReP machines - - Enable support for "Crystal CS4232 based (PnP) cards" and for the - Microsoft Sound System. The MSS isn't used, but some of the routines - that the CS4232 driver uses are in it. - - Although the options you set are ignored and determined automatically - on boot these are included for information only: - - (830) CS4232 audio I/O base 530, 604, E80 or F40 - (10) CS4232 audio IRQ 5, 7, 9, 11, 12 or 15 - (6) CS4232 audio DMA 0, 1 or 3 - (7) CS4232 second (duplex) DMA 0, 1 or 3 - - This will allow simultaneous record and playback, as 2 different dma - channels are used. - - The sound will be all left channel and very low volume since the - auxiliary input isn't muted by default. I had the changes necessary - for this in the kernel but the sound driver maintainer didn't want - to include them since it wasn't common in other machines. To fix this - you need to mute it using a mixer utility of some sort (if you find one - please let me know) or by patching the driver yourself and recompiling. - - There is a problem on the PowerStack 2's (PowerStack Pro's) using a - different irq/drq than the kernel expects. Unfortunately, I don't know - which irq/drq it is so if anyone knows please email me. - - Midi is not supported since the cs4232 driver doesn't support midi yet. - -2. IBM PowerPersonal PReP machines - - I've only tested sound on the Power Personal Series of IBM workstations - so if you try it on others please let me know the result. I'm especially - interested in the 43p's sound system, which I know nothing about. - - Enable support for "Crystal CS4232 based (PnP) cards" and for the - Microsoft Sound System. The MSS isn't used, but some of the routines - that the CS4232 driver uses are in it. - - Although the options you set are ignored and determined automatically - on boot these are included for information only: - - (530) CS4232 audio I/O base 530, 604, E80 or F40 - (5) CS4232 audio IRQ 5, 7, 9, 11, 12 or 15 - (1) CS4232 audio DMA 0, 1 or 3 - (7) CS4232 second (duplex) DMA 0, 1 or 3 - (330) CS4232 MIDI I/O base 330, 370, 3B0 or 3F0 - (9) CS4232 MIDI IRQ 5, 7, 9, 11, 12 or 15 - - This setup does _NOT_ allow for recording yet. - - Midi is not supported since the cs4232 driver doesn't support midi yet. - -2. IBM CHRP - - I have only tested this on the 43P-150. Build the kernel with the cs4232 - set as a module and load the module with irq=9 dma=1 dma2=2 io=0x550 |
