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?

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?

The IRQ is readonly in the resources tab.

Tried that. Comes back at 11.

xp-pro SP1A

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

1) I have no ethernet connection when the problems occur
2) How do I move the IRQ?

Can you tell me what the problem is? Wwhy you want to move the IRQ?
What Firewire interface and DAW software are you using?

Several folks want to know what the problem is...

The problem is that periodically the FW410 will just stop working and its
blue LED will blink rapidly. Hot-plugging does not re-establish the
connection. I have to reboot the computer and the fw410, sometimes multiple
times before it'll work. Apparently, m-audio flashes the firmware everytime
the system boots up and the only docs I can find on the blinking led talk
about the firmware not flashing properly. Obviously, this did *NOT* happen
in the middle of a session where it was working fine up 'til some point.
There must be some other situation that causes this problem but it's not
documented and their tech support is unaware of this.

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. That conclusion has been supported by a
number of other sources since that time. Pretty dumb, huh? I also have
many items assigned to the same IRQ. It sucks! I just got an A+ PC
computer certification, wherein I learned how to reassign IRQs but
found out it (for the most part) can only be done on desktops. Dell is
not the only brand that leaves the notebook owner with no change
options.

The most recent issue of EQ magazine touches briefly on the laptop/IRQ
problem and simply states that you must research different brands to
learn the IRQ placments.

I have an M-Audio Quattro USB interface. It was a nightmare! M-Audio
has since made some patches available which have helped the
performance of the interface dramatically. I now have a Firewire 410.
It operates much better even though it still shares the IRQ with USB,
video, PCMCIA, ethernet etc. etc.

Anyway, depending on your unit, you may be stuck. It's a sucky
situation. I was so angry since I had just opted for an Inspiron 5100
with 2.4 GHz P-4 with firewire and XP-Pro as what I thought would
solve all my laptop/audio problems---wrong! It is working fairly well
now with the FW-410 but it's been a hassle. Clearly, Macintosh seems
to have the edge with issues like this.

You are welcome to contact me if you have any other questions. I've
been through a lot with this question.

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.

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.

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.
