Now I knows a little bit more and that there are IRQ managers for Windows. That won't help us, but I guess there are some also for Linux. This managers won't do any thing full automatically. > For the moment I'd propose to start a page on the 64 Studio site in > order to collect information about tweaking IRQs and kernel modules. > Thank you :). > RM> Is it true that handling interrupts manually might be impossible > RM> for laptops? > > I'm not sure, but yes I guess so, some tweaks might be harder on > laptops. > The friend I had a phone call with told me that sometimes on any computer (using Windows) Interrupts won't be used, while others are overloaded and sometimes hardware gets no interrupt, while IRQs are free. He tried BIOS settings, desoldered a on-board modem, but (for Windows) sometimes he has no chance to get IRQs managed the way he tries to force them, in spite of BIOS functions, managing tools and hardware tweaks. Looking at the varying /proc/interrupts of the 64 Studio that's broken for the sound cards since I tried to install the ATI driver, it might has to do with IRQs. Okay, I'm still a noob and I could be very, very wrong, but it's something I'll read more about. A page on the 64 Studio site would be a help. If there wasn't someone asking for IRQs in the list, I never would have thought about that some troubles I have, might has to do with IRQs. Cheers, Ralf
