Changing BIOS IRQs and I/O addresses

Changing BIOS IRQs and I/O addresses

[Matt Flax]

Hello,

I have traced my problem with my sound card to the function 
'request_irq' in the intel8x0 module.

Unfortunatly the IRQ is set up by the BIOS to be 0.
This bios does not let the user alter the IRQs.

Can anyone tell me how to change the IRQ manually ?

Here is some extended info about the card :
00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] 
SiS7012 PCI Audio Accelerator (rev a0)
        Subsystem: CLEVO/KAPOK Computer: Unknown device 0400
        Control: I/O- Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- 
ParErr- Stepping- SERR- FastB2B-
        Status: Cap+ 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- 
<TAbort- <MAbort- >SERR- <PERR-
        Interrupt: pin C routed to IRQ 0
        Region 0: I/O ports at 1c00 [disabled] [size=256]
        Region 1: I/O ports at 1800 [disabled] [size=128]
        Capabilities: [48] Power Management version 2
                Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=55mA 
PME(D0-,D1-,D2-,D3hot+,D3cold+)
                Status: D0 PME-Enable- DSel=0 DScale=0 PME-

thanks
Matt

Usually, the BIOS has an option "PnP OS" or maybe "ACPI OS" to specify
whether the resources are to be allocated by the BIOS or by the OS.

If your BIOS doesn't support this, you have to configure the Linux kernel
to allocate the resources. I don't know if or how this is possible.

If you can't set the IRQ in the BIOS the only way that I know of to
change it is to change the PCI slot.  That is how I got mine set.
