P4P800-Deluxe, XP, video IRQ?

There is nothing to worry about, and there is nothing to be done about it once you're running APIC mode (with more than 16 interrupt lines) since in this mode, there is no more routing going on - it's all natively on the interrupt line where the board designers chose to put it.

You heard me: If you see more than 16 interrupt lines in Device Manager, then there's no more routing going on! The connections and sharing you see are what the hardware design imposes. If some mainboard table tells you otherwise, well then that table is wrong. Wouldn't be the first.

And it's definitely not worth thinking about. Shared interrupts have been a mandatory design feature of PCI ever since at least 1993.

Am I writing in Chinese?

There is no moving IRQs around on this system. It's cast in iron, by the choices made during the design of the mainboard. Just like on any other APIC-enabled machine.

 

Leave the IRQs alone and enjoy your system. Trying to 'fix' what isn't broken could break something.

YOU DON'T HAVE A PROBLEM TO BEGIN WITH. So stop trying to "solve" it already.

You have so many USB instances because this is the way USB 2.0 works - one EHCI controller for "high" speed devices no matter where you plug them, and a certain number of UHCI (or OHCI) USB 1.x controllers for "full" and "low" speed devices. UHCI can do no more than two ports per controller, so with eight ports, you have four UHCI controllers plus the one EHCI that takes over any port that has a high speed device on.

You just have to open your ears and listen. The assignment of USB controllers onto IRQ lines is not even a mainboard design thing, this is all interior to the Intel chipset. Do you really think you know better than them? The problem you should be working on is to get that "IRQ sharing is a problem" hype out of your head. It isn't.

Oh, and you got five controller entries because your chipset has eight USB ports. That requires four UHCI controllers and one EHCI.

really

Skaarj, I have the answer to your "problem". Find or borrow a boot floppy, and once it's started, at the a:\ prompt, type "format c:", without the quotation marks, and hit Enter then Yes. Those IRQ's won't be bothering you anymore, I promise.

 

[MDE]

You don't need to have the video card on its own IRQ. Peter's right, if it works leave it alone.

 

[Peter]

Skaarj, which part of

YOU CAN'T, IT'S HARDWIRED

is it you don't understand?

Anyway, I'm out of this thread now. The facts have been laid out, you've chosen to ignore them and instead insult me, I'm gone.

If you guys would just answer my question instead of telling me not to worry about it, then this thread would be a lot shorter. I'll make it simple for my future posts in here. Everyone that wants to spout off crap about me not having to worry about something, then don't answer any of my posts anymore. Anyone that wants to actually give me some constructive ideas on how to solve my problem, I'm all ears. Goodbye.

The problem is that there is no problem.

 

And that you CAN'T change it!
