pcchips M758LT+ sound problem S pcchips M758LT+ sound problem

I've recently bought a pcchips M758LT+ m/b which has the SiS 630 chip.
The m/b also has a 8MB Millennium DiscOnChip, which has a linuxbios installed on it. The problem is that when booting using the normal BIOS there is no sound card to be found. Doing a lspci or a cat /proc/ioports reveals no signs of a sound card on the system. When booting using the linuxbios when I do an lspci i get:

Code:

00:00.0 Host bridge: Silicon Integrated Systems [SiS] 630 Host (rev 21)
00:00.1 IDE interface: Silicon Integrated Systems [SiS] 5513 [IDE] (rev d0)
00:01.0 ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513
00:01.1 Ethernet controller: Silicon Integrated Systems [SiS] SiS900 10/100 Ethernet (rev 83)
00:01.2 USB Controller: Silicon Integrated Systems [SiS] 7001 (rev 07)
00:01.3 USB Controller: Silicon Integrated Systems [SiS] 7001 (rev 07)
00:01.4 Multimedia audio controller: Silicon Integrated Systems [SiS] SiS PCI Audio Accelerator (rev 02)
00:01.6 Modem: Silicon Integrated Systems [SiS]: Unknown device 7013 (rev a0)
00:02.0 PCI bridge: Silicon Integrated Systems [SiS] 5591/5592 AGP
01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] SiS630 GUI Accelerator+3D (rev 21)

Which includes a multimedia audio controller....
What can I do to see the audio device when booting with the normal bios?
(and before anybody asks, yes i do have the on-board sound option enabled in the bios)
Thanks

I don't think you can, if the BIOS doesn't even report a PCI address onto the kernel, the kernel won't know there's a device there on the bus at all to bind a module to it...

Wierd, I've read about LinuxBios'es for a while but never realized there were situations when they were just absolutely needed. Have you tried monkeying about with the normal BIOS, like hand assigning IRQs per device if the BIOS allows... stuff like that?

Cheers,

The BIOS doesn't allow irq to be set mannualy. Maybe I can find an BIOS upgrade and try if that works.
I've tried almost everything..
I've compiled the kernel around 20-30 times at least now, playing with different options but that didn't work.
