IRQ settings

[itsmeeh]

hey guys... does anyone know how to change IRQ settings... if I do it wrong, will it mess up my computer? thanks

You change the settings through the systems properties in the control panel. Device manager tab, select properties and then under settings choose your own settings. You shouldnt mess anything up much if you do restart in safe mode and let windows assign all the IRQ's Hope this helps

 

[itsmeeh]

is that under resources and interrupt request? and also, should I restart in safe mode and do the changes then? thanks

Yes to the resource question. You will have basic coniguration checked, and if you uncheck the automatic settings box, you will be allowed to make changes. You will have to restart your computer 'for the settings to take effect'. You dont have to be in safe mode to make changes, put do plan on going that route if you happen to mess things up. Proceed cautiously & make 1 change at a time.

thanks... i appreciate it

 

[itsmeeh]

oh yeah...one more thing... what IRQ should I change it to? how many are there?

 

[Scott Newton]

What are you needing to change the IRQ on?

 

[itsmeeh]

well, i just bought a card so I can watch TV on my PC... its on IRQ 11. My video card, modem, USB, and ACPI IRQ Holder for PCI IRQ Steering all on IRQ 11. My PCTV card does not work and I think I have to change the IRQ since its sharing it will all those stuff. What you guys think? Can I choose any IRQ like 30?

hey all,

i need some help with this as well, i did the device manager, use auotomatic settings deal, but when i went to change the irq it gave me a message saying "this resource setting could not be modified" this is a PnP sound card. do i have to turn off the PnP on the board or somthing?

thanx

there are 14 IRQs but some of them cannot be changed. Are you sure its an IRQ problem? Is there a yellow exclamation point next to your tv card in device manager? If not there might be some other problem with your tv card.

 

[itsmeeh]

hhhhmmmmm... it says the card is fine and there are no conflicts... but a lot of people have this problem... if its not the IRQ then I have no idea what it would be... have any idea what would the problem be? thanks in advance

 

[itsmeeh]

and also... like what nebakanezzar said... how do you change the IRQ if it says it can not be modified?

 

[azkiwi]

uncheck the automatic settings box first -- then you will be able to modify the settings. However, you might be better off leaving it Pnp and taking out some other cards first. After this card is installed the other(s) may install themselves again.

Some cards only want to install at a certain spot, while others are more flexible.

 

[itsmeeh]

i tried to uncheck it and change the settings but it does not allow me to do it... how can I manually change it? Thanks in advance

there's actually 16 irqs

 

[convex]

go into your bios and disable PnP aware OS

hey guys,

there are 16 irqs from irq 0 to irq 15...

most of them are reserved for devices on the motherboard such as ps2 ports, ide/floppy controllers, etc...

the only ones u could actually use are 3,4,5,7,9,10, and 11...

some pci slots share an irq, so changing it for one slot will also chage it for the shared one...u'll have to use different slots to get around this...

windows won't let u modify the irqs directly...not when it's runnin at least...

u can, however, change how it assigns the irqs...

itsmeeh, pci cards r required to have the ability to share irqs according to the pci specifications...however, it is still possible that there is one too many devices on that irq...r the other irqs i listed above free to use, or do they all have something assigned...what do u mean "it doesn't work"...r u sure it is a hardware problem and not software related??

I thought i had an IRQ problem fitting a Network card,after moving it to a different slot still would not work.Tech department said even though your Motherboard is only 18 months old (ASUS)the driver`s need updating at the very least and probably 1 or 2 other things,worth a try?.

Changing IRQ's after the fact can be frustrating.

PNP OS should be toggled on and the 'reset configuration data' turned on at the right time with the last reboot, it will default to disabled with the reboot anyway.

Remove your devices via the dievice manager and shut down, then remove all of the cards. I am assuming since the TV in card took IRQ 11 it is placed high, probably in the PCI slot right under the AGP??? That spot is better used for a second vid card, firewire input, video editing card (ie, Pinnacle, and the others), stuff like that.

Install the TV in card in a lower PCI slot and boot, it should default to another IRQ, hopefully, then add the other cards one at a time, double checking the IRQ assignments each time. I have run into this problem before and you can solve it with the correct installation of the cards, ie, proper order.

There is one other way to force the issue and I have gotten it to work. Some sounds card will take a move to a different IRQ you dictate, in your case, move it to IRQ 11, forcing the issue (it will tell you it is conflicting, but continue on anyway), reboot and hit del to get into bios FIRST, make sure PNP is on and the 'reset configuration data' is toggled on for the reboot. YOu can set the PNP to off again later.

This way, when winblows starts, it will force the sound card onto 11 and kick something else off, like the modem, your USB will probably stay, and your TV in will work.

AS a matter of fact, now that I have thought about it, the reason your TV in card doesn't work is because of the modem and the modem wave device anyway. I had this problem and I solved it with some creative card shuffling, took awhile.

lol, u guys go through a lot of trouble just to get windows to allocate your irqs correctly...

the easiest and best alternative IMHO is to try changing the irq allocation algorithm of windows found in dev manager >> sys dev >> pci bus >> irq steering

in addition to the linked slots, my abit kt7-raid's integrated devices must share irq's with the pci slots...so, the following slots and devices share an irq: the agp with pci1, raid controller with pci2, and usb controller with pci slot pci4,pci5,pci6...there is no way around this...

so, make sure your tv card isn't in pci1 (which usually shares the agp irq) and not in pci4+ (which usually shares the irq with pci slots below it and the usb controller)

best of luck to u
