Oh, I almost forgot, the RedHat sndconfig +failed detecting it ;) + So, the big problem still remains, because the sb module wants a +8-bit and a 16-bit dma, which we could not allocate for vibra... it supports +only two 8-bit dma channels, the second one will be passed to the module +as a 16 bit channel, the kernel will yield about that but everything will +be okay, trust us. + The only inconvenient you may find is that you will have +some sound playing jitters if you have HDD dma support enabled - but this +will happen with almost all soundcards... + + A fully working isapnp.conf is just here: + + + +(READPORT 0x0203) +(ISOLATE PRESERVE) +(IDENTIFY *) +(VERBOSITY 2) +(CONFLICT (IO FATAL)(IRQ FATAL)(DMA FATAL)(MEM FATAL)) # or WARNING +# SB 16 and OPL3 devices +(CONFIGURE CTL00f0/-1 (LD 0 +(INT 0 (IRQ 5 (MODE +E))) +(DMA 0 (CHANNEL 1)) +(DMA 1 (CHANNEL 3)) +(IO 0 (SIZE 16) (BASE 0x0220)) +(IO 2 (SIZE 4) (BASE 0x0388)) +(NAME "CTL00f0/-1[0]{Audio }") +(ACT Y) +)) + +# Joystick device - only if you need it :-/ + +(CONFIGURE CTL00f0/-1 (LD 1 +(IO 0 (SIZE 1) (BASE 0x0200)) +(NAME "CTL00f0/-1[1]{Game }") +(ACT Y) +)) +(WAITFORKEY) + + + + So, after a good kernel modules compilation and a 'depmod -a kernel_ver' +you may want to: + +modprobe sb io=0x220 irq=5 dma=1 dma16=3 + + Or, take the hard way: + +modprobe soundcore +modprobe sound +modprobe uart401 +modprobe sb io=0x220 irq=5 dma=1 dma16=3 +# do you need MIDI? +modprobe opl3=0x388 + + Just in case, the kernel sound support should be: + +CONFIG_SOUND=m +CONFIG_SOUND_OSS=m +CONFIG_SOUND_SB=m + + Enjoy your new noisy Linux box! ;) + + -- cgit v1.1
