Linux install problem

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

Norman,

The most common way to change Interrupts for device is through the BIOS. You have mentioned that there is no relevant setting in your BIOS to do this. Have you tried flashing your BIOS to the latest version? Try contacting HP regarding this.

HP deliberately dumbs down the bios so that settings cannot be changed and I do not have the time, presenty, to alter the bios with the Phoenix Bios Editor.

I've dealt with HP before -- once, and never again -- so I'm not surprised if you're frustrated, but if you have time to do anything, I would think that you have time to flash the BIOS. What am I missing?

The fact that I would first have to extract the bios from a download that flashes after DL. Then that I would have to reconstruct the tables, then I would have to add the tables that are missing, then I would have to override the table locks, then I would have to put the whole mess up into Pheonix Bios Editor and compile it.

Then finally, hope that I did it all right the first time and flash the BIOS because if I booboed anywhere the bios would have to be replaced.

The last time I did this, it took over a month to do correctly and I was still strongly hoping when I flashed the BIOS. Unfortunately, HP undid my work by re flashing the bios in a repair.

It seems that Novell fouled up when writing the install of OpenSuse 10.3. When the install writes the /etc/fstab it writes two blank lines at the end and adds a few unprintable characters. This screws up the load process on this MB. This did not happen on the old MB (3EB6) however. Also,this occurred with three different DVD iso DL's and burns.

At least this is true for run level 3. There were also several errors in the X files as well.

Now I have to straighten out run level 5.

At least now I can boot to run level 3 and start X from there, I can also run 3d graphics and the sound does not loop.

Still need to remap a few devices, so I am not closing the question.
