This system also has Radeon PCI video card that uses irq 5.

In win98 the video card uses irq 9 and the sound card uses irq 5
Our first try was to assign irq 9 to the SB-16 so to the kernel we added:

  # SB16 sound card support
  device          sbc0 at isa? port 0x220 irq 9 drq 1 flags 0x15
  device          pcm

rebuilt the kernel and tried ./MAKEDEV snd0. Now the SB-16 seems to be
recognized. From dmesg:

  sbc0: <SoundBlaster 16> at port 0x220-0x22f irq 9 drq 1 flags 0x15 on isa0
  pcm0: <SB16 DSP 4.13> on sbc0


but there is no such device in /dev.

Needless to say sound is not working and we are quite lost. 

The system has a built-in video which is being overridden by the PCI card the
relavent messages here are (I think)

  pcib0: <Intel 82443BX (440 BX) host to PCI bridge> on motherboard
  pci0: <PCI bus> on pcib0
  pcib1: <Intel 82443BX (440 BX) PCI-PCI (AGP) bridge> at device 1.0 on pci0
  pci1: <PCI bus> on pcib1
  pci1: <ATI Mach64-GW graphics accelerator> at 0.0
  pcib2: <DEC 21152 PCI-PCI bridge> at device 2.0 on pci0
  pci2: <PCI bus> on pcib2
  pci2: <ATI model 5144 graphics accelerator> at 9.0 irq 5

We can't find specs on the SB-16. Can it use irq 9? If this is the problem how
can we assign irq9 to the video card?

thanks for any pointers
