Dell Notebook computers sharing IRQ 11
I have a dell notebook and it's firewire port shares IRQ 11 with:
IRQ 11 Dell C840 OK IRQ 11 Intel(R) 82801CA/CAM USB Universal Host Controller - 2482 OK IRQ 11 Intel(R) 82801CA/CAM USB Universal Host Controller - 2487 OK IRQ 11 3Com 3C920 Integrated Fast Ethernet Controller (3C905C-TX Compatible) OK IRQ 11 Texas Instruments PCI-4451 CardBus Controller OK IRQ 11 Texas Instruments PCI-4451 CardBus Controller OK IRQ 11 Texas Instruments OHCI Compliant IEEE 1394 Host Controller OK I'd like to move it over to: IRQ 4 - Com Port IRQ 5 - Modem IRQ 6 - Floppy Controller (Since I don't use either of these devices.) Any idea how I can accomplish this? |

Any idea how I can accomplish this? I will hazard a guess... If you're not using the com port, modem, or floppy controller see if you can disable them in the bios (I know the bios on my dell latitude doesn't allow this level of control but...). Then, back in windows, go into the device manager and manually change the configuration on the resources tab for the firewire controller. You might also try removing the firewire controller through the device manager and then restart windows and seeing if it uses an open IRQ when it's found after windows gets going again... Which windows are you using? Kirk |

I believe you might see the most improvement by moving the ethernet
controller off of irq 11. Avenger. |

om... After struggling with this same issue for several months, I was told by a Dell upper level tech support person that I cannot change the IRQ assignments on my notebook. I don't think I can with mine either, but I haven't sweated the issue because it works just fine the way it is (I'm using an MBox with a Sony laptop and external Firewire drive). Makes we wonder if sheets has an actual problem that needs solving, or if his efforts are more of a pre-emptive strike aimed at "potential" problems. Clearly, Macintosh seems to have the edge with issues like this. Which "issue" is that? We've got both and so far I've yet to establish any clear advantage to one or the other. The Mac may not have IRQs to contend with, but it's got its own configuration issues. Six of one, half a dozen of the other. Lorin |

I think that some people would be really surprised to hear that the old IBM mainframes, with zillions of I/O devices all over the place, many running fast and furious, routed essentially all I/O through 1 IRQ. They did this with clock speeds as low as 1 MHz or less. |

Unless your device that is performing poorly needs a truely huge amount of
processor power (Gigabit ethernet or equivalent is about the only thing that comes to mind, and what would that be doing on a laptop ;=) ), there is little reason to try and change IRQ. If a device really requires that, either it is so poorly deisgned as to be considered broken or the driver is likewise poorly designed. Modern laptops should be able to cope with almost any combination of devices with no problems. Marc Reinig System Solutions "sheets" wrote in message om...

Modern laptops should be able to cope with almost any combination of devices with no problems. Yeah, this is what Dell says too. But while this may be true in theory, it doesn't fly in practical application. I have the same problem with a Dell C840. I have tried many different 1394 cards, storage devices, and input devices (preamps), as well as many different drivers for each device & all of them have problems. I have completely reformatted and reinstalled from the OS up 5 different times in failed efforts to fix the drivers. All this leads me to believe that there is an issue with the laptop. It works fine 90% of the time, but will glitch occasionally when recording to or reading from a firewire device. That isn't good enough for a critical live-recording situation. So I guess I'm back to the dedicated HDR... PS |
