Quote: Errrmmm... That's not exactly what I meant. I know that it's a more awkward way of assigning IRQs to PCI slots, but what I don't understand is how to use that table to figure out how to make a spcific PCI slot use a specific IRQ. I don't know why Abit [or Award, if it was their idea] would chose to do it this way instead of the "PCI no. X use IRQ Y" way. try going to thier web site and see if they have a support forum... I am sure someone thier has the infor you need...

Sure try this.... http://duxcw.com/faq/irq/irq.htm Also your PCI slot has a IRQ that you can assign but it also is connected to other devices like your usb port...etc (USB not a PCI card but it will use the same IRQ as the PCI slot) so it almost like being a real PCI card... takes the same resoures...

Quote: No it is not that hard to understand - I understand it perfectly well, the point I was trying to make is that my soundcard doesn't seem to understand this. Whilst other devices in my system don't seem to mind all pretending they're on the same IRQ [or allowinbg Windows to do so] it seems that my soundcard needs to genuinely be on the IRQ that it wants [10], either that or it doesn't like sharing an IRQ - which it may or may not be doing as I can't see what IRQ's their really using cos of the whole ACPI/virtual IRQ thing. A. Greetings to the Society for Unnecessarily Patronising People Sorry I wasnt trying to be funny... I was trying to say that in your case disableing the ACPI may help you.... it depend if you can set IRQ 10 just for your soundcard... that may involve moving PCI cards...ETC... But as IRQ 10 isnt use for any of the system board stuff like system timer, hard drive controllers, USB ports then there is a very good chance that this can be done...

Quote: So to sum up what's been said in this thread - I can have ACPI & the ability to use hibernation & have my soundcard cease to function @ random, often within a couple of mins [sometimes it's less than 30 seconds] of starting to watch a video file or play a game - OR I can do without ACPI & hibernation & hopefully be able to get my soundcard [Videologic Sonic Vortex 2] on IRQ10, on it's own, as opposed to being on 12 with a bunch of other stuff as it is now. Is this right? Uuuuummmmmmmmm yeah that about right.......

Oh yeah I almost forgot.... if your motherboard isnt ACPI compliant or on the BAD list that MS has then XP isnt suppose to install ACPI.. http://www.microsoft.com/technet/treevie...dc_mcc_htev.asp and if this isnt an issue then why does MS give you this? http://support.microsoft.com/default.aspx?scid=kb;en-us;Q216251 Well thats it for me... if you believe that there arent any issues here then thats fine but when MS says they have issues I would tend to believe them.......

Although some problems with IRQ sharing exist, most are related to high-bandwidth devices. Windows XP Professional manages IRQs using a first in, first out (FIFO) stack. The more devices that share a single IRQ, the longer it takes to traverse this stack, which can have a system wide performance impact. Performance problems might be reduced if high-bandwidth devices such as high-speed network adapters and high-end Small Computer Standard Interface (SCSI) controllers, for example, use different IRQs. More flexible interrupt handling models are available on newer x86-based ACPI systems that support the Advanced Programmable Interrupt Controller standard. Systems that incorporate the Advanced Programmable Interrupt Controller have access to more interrupts, which avoids the need to share interrupts. Most x86-based systems do not support manual configuration of IRQ settings. However, a few do offer this capability as a troubleshooting feature. If you are experiencing problems with system lockups or stability, you have two alternatives: If your system firmware supports manual configuration of IRQ settings, as a troubleshooting method, try manually assigning IRQs to specific PCI slots by using the configuration options in the BIOS. If you need to manually assign IRQ addresses for an ACPI-compliant computer and the BIOS option to disable ACPI is available, disable ACPI before installing Windows XP Professional. However, remember that it is best not to change the BIOS default or automatic settings unless you have a specific reason to do so. If your system does not support manual configuration of IRQ settings, try moving high-performance peripherals to another slot. and this is from this DOC that is found on MS site.... http://www.microsoft.com/technet/treevie...dh_dmt_kasl.asp EEEEAAAHHHHH Say agian??? what was that....

Quote: Sigh, the point is there is normally, on a PCI card /Windows based system, no reason to disable ACPI. The hardware and software is built to use it. And ACPI is not really assigning IRQ 9 to anything, read BladeRunners post, doesn't really need any elaboration. H. both the main systems that I use has all PCI... both motherboards dont even have ISA slot all my hardware is less than 6 months old and is 100% ACPI compliant(or so they say) so why do I get IRQ conflict when running ACPI?

Originally posted by BladeRunner [/i] As long as you have the hardware then ACPI is one of the best things ever to come from Microsoft/Intel. --------------------------------------------------------------------- The concept is good but to bad MS doesnt make everything in my system so that it is compliant with their standards -------------------------------------------------------------------- No more limited by 16 physical IRQ's. ---------------------------------------------------------------------- Yep software waves a magic wand and does away with hardware limitations.... ------------------------------------------------------------------- No more have to shift things around whenever I wanted to add new ahrdware. --------------------------------------------------------------------- Even MS says moving PCI cards may help -------------------------------------------------------------------- No more sitting with pencil & paper for hours on end trying to work out which devices could use which resources, which could share, which couldn't. --------------------------------------------------------------------- Yeah now your having IRQ conclict and cant do anything about it.... And sitting for hours? I never did that with my old systems.... 4 com port 16 IRQ's not a lot to figure out.... -------------------------------------------------------------------- It's now just plug everything in and go. -------------------------------------------------------------------- Ohh in a perfect world ---------------------------------------------------------------------- I'm sure people must be aware that although all hardware devices appear to be using the same physical address (usually IRQ 9) they are in fact using virtual addresses. For example my NIC is running on IRQ44 if I remember correctly. -------------------------------------------------------------------- Like virtual memory.... a good thing but you dont want to use it... --------------------------------------------------------------------- If somebody has older hardware or more than one ISA card then I can see the logic behind choosing "Standard PC". You are using legacy devices and should set your OS to run in "legacy" mode. --------------------------------------------------------------------- You mean slow mode -------------------------------------------------------------------- However if you've got relatively new hardware then ACPI has to be the way to go, purely from it's simplicity. [/b] --------------------------------------------------------------------- If it works for you then thats the way to go... I havent had any good exp with it and most of the ACPI concept havent been implimented so thats why its not working the way it should.....ACPI is mainly for future use.....(IE turning your toaster on and off) This is what MS invisions..... so why use it now when I dont have a PNP toaster??? I think I will use it in the future when they have worked the bugs out of it....

Quote: Right, turn OFF ACPI, use a ISA Video Card and switch back to 5,25 inch floppies. WTF ? There is no point with current PnP hardware to stubbornly trying to assign IRQ yourself. Unless you have very old or very exotic hardware, you should of course install XP with ACPI if you are planning on using any power saving options. If you install from scratch, you have to resort to mild violence not to install ACPI. H. 1. if you disable ACPI you dont have to assign IRQ yourself, your PNP BIOS and Windows can still assign IRQ and most of the time this works fine.... But it allows you to change them if you need to... and it allow Windows to assign your devices to IRQ's other than 9.. 2. In the realm of PC's any thing older than six months is old and alot of people are installing XP on 400 or 500Mhz machines that may not be 100% compliant with ACPI... (IE E machines are a prime example) 3. ACPI and APM are differant if you disable your ACPI only hybernation and auto shutdown are affected as they require ACPI the other power saving features (monitor off, hard drive off) are unaffected) 4. If you istall from scratch you have to hit F5....????if that is mild violence then I guess I need anger management counseling...

also the PNP OS setting in your BIOS does this if set to yes or enable - the bios only assignes IRQ's to the hardware that is required to boot....IE hard drive... and allow the OS to assign the rest... if set to no then the BIOS assigns IRQ to all hardware that requires them... Which windows XP then reassigns to IRQ 9....

Actualy I have made a DOC that takes you step by step on how to disable the ACPI and issign IRQ manualy weather you are doing a new install or you just want to change an existing install.... The article referanced above says that you have to reinstall the OS but I have found that this is NOT the case... I run all my PC as standard PC's with the ACPI off and have no problems with any of them other that the cant hybernate or turn themselves off... I leave my systems on all the time and the ones that are turned off are my childrens and they just hit the power button.....Hard shut down!!! Agghhh bad for the OS!!! I dont know my system crashes more than theirs.....Maybe because windows doesnt get to save all the setting that they have changed....I understand that the article says that windows can do this IRQ sharing with everything on IRQ 9...but all of my hardware is not the latest and greatest....so it ended up having alot of conflicts....during all my years as a computer geek I have been taught that IRQ sharing is BAD and have dealt with IRQ conflict and I am sorry to disagree with MS but I still have IRQ conflict...and I have found a way to fix them....I really dont see the need to put share an IRQ when i have 3,4,5,7,9,11 open and free...Irq sharing would be fine if it happened after all of the IRQ were used... But it doesnt it just sticks 10 devices on one IRQ...so that poor IRQ end up in a circle jerk with all these devices pushing it around... I still think that picking on the single IRQ is a bad thing...

I made a DOC file that explians how to disable ACPI and manually assign IRQ's it has screen shots and more... email me and I'll send it to you....
