WinXP won't let me change any of the hardware resources in the device manager, namely IRQ settings. The little checkbox that has "Use Automatic Settings" and the "Change Settings" button are both greyed out, and I don't know what to do.

[Reply or follow-up to this message]

Same problem. Im experiencing freezes every time I try to play Counter Strike. I supposed this was caused by the irq sharing of the video card (Hercules GeForce II MX) and the isdn Modem (Trust). I tried to change "computer" settings under the device manager to "standard pc" (no acpi), but that didnt work. I tried to change irq from bios no matter what i do the two slots share the same irq. I need some advice.

[Reply or follow-up to this message]

With XP and newer motherboards sharing IRQs is not a problem. They are designed to share and with the proper hardware and drivers there will not be any conflicts. I believe 7 and 11 are the most common to be shared. I know I have about 5 devices using IRQ 11 and have no problems. I got a new motherboard that didn't like XP so I traded it for one certified to run XP. Runs like a champ.

I've gone through three newer motherboards and am having problems with IRQ sharing, well at least i think i am because i've done everything else. All my drivers are WinXP. I've modified countless BIOS settings and even tried other video/sound cards. No help.

Hey I have exactly the same problems that you all are having :( I still have not figured out how to fix the issue

[Reply or follow-up to this message]

There is a good Ms Softee explanation for this problem,and IRQ 9 seems to keep popping up as a common thread. See this link about this issue at: http://support.microsoft.com/default.aspx?scid=kb;en-us;Q314068 disable ACPI support in the BIOS setup Next, you'll need to switch Windows from ACPI to Standard PC support. To do this you will need to reinstall Window 2000 or XP with the "Repair option." Windows sets this up during the Detecting Hardware phase of the install and there is no way to change it without reinstalling. Fortunately, when you reinstall using the Repair Option you keep all your customizations, including desktop settings and installed applications.

[Reply or follow-up to this message]

I have the exact same problem. Every card in the PCI slots, My AGP port and my USB controller is using IRQ9. I tried shutting IRQ9 down in the BIOS but XP is still using it. Normally, you'd uncheck automatic settings and change the IRQ. But in XP the checkbox is greyed out. My counterstrike is also freezing and "looping" sound. P.S. checkout the CS server @ 66.28.23.87:29025 its Runing CSGuard and Cheating Death. I'm Co-Admin there, tell em Ritchie sent you.

i´m having same kind of problem, my bios says that my display card is in irq 11 and xp says 16 and nothing seems to help to change it

[Reply or follow-up to this message]

You can also change from ACPI to Standard PC in you device manager. 1: press Windowskey + Pausebreak to enter system properties. 2: Open 'hardware' tab. 3: Click 'Device manager' 4: Click on the + symbol in front of 'computer' 5: Double-click 'Advanced Configuration and Power Interface (ACPI) PC' 6: Open 'driver' tab 7: Select 'update driver' 8: Select 'Install from a specified location' 9: Select 'Don't search, I will choose the driver to install' 10: Select 'Standard PC' (maybe you need to de-select the 'Show compatible hardware' box) 11: Click next and follow instructions. After reboot, WinXP will re-detect all devices and re-map all IRQ's. But be aware ... you can not 'roll-back' this driver to ACPI. After you've installed the standerd PC driver you machine also won't shut-down automatically anymore when you quit Windows. You will need to power off manually when it says 'It's now safe to turn of your computer'. Good luck, Frank.

Thank you sooooooooo much. It seems obvious now that I've been told, but I never would have figured it out.

[Reply or follow-up to this message]

Frank your solution is excactly what I need since my bios will not allow me to disable ACPI. However, it look like ther is a step or two missing between steps 9 and 10. You say that I should specify a location but then you don't say what location to specify. Should I point the file open dialog at my win2k disk (which directory?)? If so, which directory? Also, it seems like even if I do this, then w2k will just pick the best driver. Don't I need to select 'Display a list of ...' at step 8? Anyway, thanks in advance.

well contrary to what M$ says about IRQ sharing being no problem, and with a few people that obviously are NOT gamers.....Sharing IRQs IS a problem.... My Video card is sharing IRQ16 with my sound card, and 2 USB controllers, and one other dodad i cant remember right now.... When i disable all other things on that IRQ other than my Video card I get more than a 1200 point increase in a popular benchmark (3D Mark 2001se).. Thats a BIG increase in performance....and by simply disabling the other devices... What id like to know is why WinXP assigns ALL of the most demanding hardware onto the same freaking IRQ, when there are several unused IRQs?

I have a problem or should say had a problem I tried to change to standard pc through device manager. using the update driver section when I rebooted it prompted me to reinstall winxp i selected the repair option and it did it's thing, it reinstalled the ACPI configuration I thought oh @#%& but everything seems to work fine now and yes my video card, ethernet card and sound card all share the same irq I'm wondering if this is more a corrupted file issue rather than a conflict with irq's? Just a thought!

Hi, I just changed my system back to standard pc but...when i go into device manager i now have different irq's but it is still greyed out in use automatic settings...how do i change this. I checked my cmos and there is no refference to acpi there...could it be called something else and where specifically is it..eg advanced tab..etc..or is there some other reason why it is still greyed out? Any help would be greatly appreciated. Phantas

Try this on for size...

http://support.microsoft.com/default.aspx?scid=kb;EN-US;299340

Talks about forcing in a system hardware abstraction layer (HAL), preventing ACPI 
from being chosen as the default during the reinstall.

it is possible, but microsoft don't advertise it on msdn... boot with xp cd, choose repaid an xp installation assume d: is your cdrom, expand d:\i386\halacpi.dl_ c:\windows\system32 this will extract acpi compliant hal, hardware abstraction layer, to file halacpi.dll next delete current hal.dll, and rename halacpi.dll to hal.dll done xp might ask you for the drivers again for some hardware

I installed WinXP on a brand new Soyo Dragon Plus and it's completely log-jammed on IRQ 11. I don't think your theory about WinXP and newer motherboards is accurate. I have been reading as much as I can on this issue and I fine that VIA chipsets seem to be a common factor.

I was having the same problem with my GeForce4 MX 440 card freezing up during games. I noticed on my machine that a lot of devices share IRQ 9. However, going to the VIA Chipset website and d/l the latest AGP drivers seems to have solved my problems. I do think that I would still gain better performance overall by being able to individually assign IRQs to some of these devices so I will be following some of the advice below.

The change to "Standard PC" from ACPI worked wonders for me. Thanks! All my hardware was trying to jump on IRQ11. I tried the remove devices and reinstall 1 at a time to no avail. It worked great until the second I installed my network card and rebooted then they all jumped onto 11 and the fun resumed. This ACPI to Standard PC fix works wonders.

Thanks for the advice. I got it to work by following your post, but in a slightly different way. My system is set up so I couldn't boot from the CD-Rom drive (it's on a SIIG IDE-133 PCI card). Anyway, all I did was boot into my regular XP installation, put the XP CD in the drive, go to Start -> Run and type CMD. Hit OK and then type the following: EXPAND D:\I386\HALACPI.DL_ C:\WINDOWS\SYSTEM32\HAL.DLL It should let you do this. Then, just reboot your system and ACPI should come back to you. With my system, it gave me both ACPI and Standard PC in the Manage Computer screen. All I had to do was to Uninstall StandardPC, reboot, and all was fine. Lauren

XP does'nt allow changing IRQ's, try going to your pci comfiguration in your bios setup and change the irq's to the assigned pci slots, also you can fool around with your pci slots on your mb, and try different slots for your cards, certain devices should be not shared, for instance your video card is fussy what it resides with. Good luck Robb

Ok here is a trick which will do the same without the Need of reinstalling....I stumbled upon it quite by accident though... U need to have ur PC updated to SP1, Ppl with Pirated XP sorry, SP1 wont work... Now pop in ur XP cd and restart and boot from CD (Enable it from BIOS), Now get into Repair Prompt... Now goto C:\WINDOWS\ServicePackFiles\i386\ (assuming XP is in C:\) Now copy HAL.DLL to C:\windows\system32\... (Replace the Existing file), Restart..Tada U have a standard PC...Now reconfigging IRQ's I dont know bout that But this will make ur PC "Standard PC" also U will have to re-install all Ur Drivers...Most of em Willl be Automatic but som U'll have to provide...

I followed the steps outlined by some of you in this thread...i.e., turned off the ACPI in my bios, even reformated my hard drive and upon reinstalling XP, hit the f5 key when the computer gave the option to hit the f6 key...this led to the choice to set the computer to a Standard PC vice ACPI PC. With everything loaded, I still cannot reassign IRQ's! the automatic settings are greyed out in the device manager. Any more suggestions?

I had done the same thing and wanted to revert back to the ACPI setting. To get round this I restored my PC back to an earlier time before I made the change and this solved the problem.

Hello guys. Read above posts with much interest! My recently built XP Home SP2 system, using a second hand MoBo isn't showing up the onboard IEEE 1394 in device manager or allowing that port or any PCI device in any PCI slot to function. AGP is fine, so is USB. MoBo is stable. PCI bus not Oc'd (set at 67) .So I guess that means a hardware or ACPI Problem. I'd love to test the above IRQ conflict reloving solutions. However, a complication for me is that I have a dual core CPU - AMD64 X2 3800 on an MSI Neo2 Platinum MoBo. If I ditch the ACPI, by whatever means, in favour of a standard PC config-won't I lose dual core CPU recognition?

[Reply or follow-up to this message]

I am also stuck with the same problem. We got a new Dell Precision WorkStation 670 which is having Dual Xenon processors. One of the PCI cards we use doesnt work fine in IRQ sharing mode. I tried reinstalling software with Standard PC config. But still the automatic settings is greyed out and now the sharing is more on IRQ9, IRQ10 and IRQ11 where all of our PCI boards are installed along with the Sound drivers, USB controllers and Storage controllers. Anyone have any idea how to change the IRQ assignments..plz..? -Pav.

This Microsoft KB document might help you. If you want multiprocessor support without ACPI, then you want the "MPS Multiprocessor PC" HAL (Halmps.dll). Note: I have not yet tested this, or any of the provided methods for changing your HAL, so use this information at your own risk.

http://support.microsoft.com/kb/309283

[Reply or follow-up to this message]

To switch from Standard PC HAL to ACPI HAL this is what I did using Windows XP.  
Find the latest copy of halacpi.dll on your system.  It may be in the ServicePack 
or Driver cache directory. 

1) Boot to recovery console
2) rename the \windows\system32\hal.dll to hal.bak
3) copy halacpi.dll to \windows\system32\hal.dll
4) restart Windows
    If all goes well, the ACPI HAL will load and all drivers will
get re-installed.
    If something goes wrong, (this didn't happen to me)
boot to recovery console and restore the original hal.dll
