I sent an HP dv9225us to the factory for repair. During the repair, the motherboard was downgraded from a Quanta 3Eb6 to a Quanta 30B6. HP claims that the 3EB6 motherboard has many problems, and this is why the change.
Prior to sending the NB to HP for repair, I had OpenSuse 10.3 running on the NB without problem. After the repairs, I initially could not get linux to function. Eventually I managed to install OpenSuse 10.3 by setting the flag nolapic.
After several days, I managed to locate the source of the problems. There is an interrupt conflict between the Video and the sound card. The Video is an NVidia Geforce Go 7600 and the sound uses the Compac Presario V6133CL (hda Intel compatible) chipset. Both use interrupt 11. The MB chipset is Nvidia MPC 51, but I am not sure which particular set. The CPU is an AMD tl-60 and there is 2 gigs of ram installed. I am using the 64 bit version of OpenSuse.
Since I have established the source of the problem, I now need to solve it; I need to change the interrupt mapping, probably for both, of the video and the sound cards. I have howto’d device interrupts but can find nothing that tells me how to change the interrupt mapping via software. A bios change is not possible with the installed bios. This information should be common to all Linux.
Can you tell me how, or provide information that would tell me how to change interrupt and device mapping in Linux?
Thank you
