| |
Hi all !
I recently bought an Adaptec 2940, and my bios decided to allocate the same IRQ for this card and my video controller, a Diamond V330 (AGP!)
The consequence is that I cannot run the xserver, it totally freezes my box...
I suspect that it is a bug in the bios, but for the moment Gigabyte had not answered to the questions I mailed them, so I wonder if it is possible to do the buggy bios work in a part of a linux kernel. However, reading the sources, I suspect that the kernel totally assumes that the bios has done his job well, and can use the peripherals with their IRQ settings (or maybe I have read too fast).
I do not expect you to solve that problem, you certainly have others things to do, but if you could give me some clues in order to do that, I would appreciate.
I had an other idea, which would be to write in the bios memory the good values for the peripheral, and ask the bios not to reset the configuration data, but I don't know if it is possible. Maybe the bios stores only the IRQs reserved for legacy ISA cards, maybe it stores the information Bus/device/Irq in it, but I'm not a bios specialist, so, I don't know.
Thank you for your help, sorry if you find my mail off-topic (you can flame me !), and continue your good job !
