Ok, people what is the deal with irq nine and why is everything I have being jammed on it? I have spent three days trying to get my hardware to go where it is suppose to be and everytime I load up the drivers they switch from the irq settings they are at to 9. This in turn is giving me grief to get on the net. I load up the pppoe program and It works fine I connect up faster than ever...soon as I reboot, it goes bye bye. and that software takes forever to load up. Now I can connect to the server all day long...but I can not surf at all. Before you all do the simple thing I have reworked all the hardware in my system, I pulled it off the windows control to my bios, been in and out of safe mode. What I can not do is move the irq itself no matter what it shows greyed out and It will not let me move it from irq9.
Now everything else in my system works perfect. Except that pppoe software from Enternet. The two place I am having the problem seems to be a conflict with...well, was in the past I'm not sure anymore if this is the case...but my network card crashed in to my soundcard I moved it off irq9 then and everything worked fine and that was on 98. I know it isn't the software I use to connect. Because I went back to the older version to which I connect up just fine with and it wont let me now either... simply asked here as I babble on ... HOW DO U GET IT ALL OFF IRQ9???? Thanks for any help James
 
This <i> feature </i> of win2k is due to it's support of multiple cpu's, PCI buses, etc. While win2k thinks you've got an ACPI machine(All machines in the past few years) it's impossible to change the IRQ.

I read the solution to this a few months ago so my answer is a bit hazy. You've got to open the<b> system devices </b>section of <b>device manager </b>and find the device <b>"Advanced Configuration and Power Interface (ACPI) Bios"</b>. Upgrade the driver for this device and choose to manually assign a driver. Select "plug and play bios (fail safe)" or "Standard computer" or somethin along those lines {Sorry I can't remember the exact device}.

Warning! Changing this device to an incompatible driver could stop your computer from booting, so don't do it if you don't know how to deal with this.

If you need some more details post again and I'll have a fiddle on a win2k system I've got just for that purpose.
 
Thanks for the tip. So I can alter my irq settings afterwards? if it dont work be a six hour round trip to reinstall back to me thru 98. So I can come back on here
 
Just change it to standard pc like the other post told you. The only thing is that you will have to reinstall all drivers for your machine such as video, sound card, etc. It will be just like you have installed the operating system for the first time. All your IRQ's will then be re-assigned when you look at them again.
 
Same here... EVERYTHING has dumped on IRQ 9: sound blaster, video, ATA100, ethernet! If anyone has the location of detailed and specific info on this it would be greatly appeciated. Thanks!
 
I have run into this, I have two 2000 systems, one all the cards are on IRQ 11, and the other on IRQ 9. I haven't run into any really harsh problems. One system has Video, DVD decoder, Sound, Ethernet and USB on irq 9 and I haven't had a problem, it's on 24/7 also. But that dosen't mean that there isn't an issue, I have run into a problem like the one you are describing, I have found that there are issues with some motherboards about the order in which the cards are installed, and which PCI slots they are installed in.

Try getting the most recient released Bios for your motherboard, try reorganizing the cards in your PC, and install the NIC first and test it for a while before you re-add your other cards.

As a note, I generally install cards in this order:
Video
Storage(SCSI, ATA100)
Nic
Sound
Decoder/Multi media
 
I've just done this and it worked without a hitch.
The item to change is actually listed under <b>Computer</b>, not <b>System Devices</b>. Open the properties for <b>Advanced Configuration and Power Interface(ACPI) PC</b> goto update driver and choose to select a driver from the list. Then click <b>Show all hardware in this class</b> and select <b>Standard PC</b>.

When the computer restarts you'll have to reinstall all your drivers as hgranero pointed out. On my machine win2k managed most of them automatically, I only had to give details for my graphics and sound cards.
Now I've got network on 9, sound on 10, and graphics on 11.
Hope this is detailed enough for you cirrus.
 
hey cxg thanks! knowing the right place to look was a big help; and the rest was cake.

I tryed this out on my K7V first as this machine is pretty well trimmed down hardware wise, I'm also using this machine as my ICS server... the new set up lightened the load a bit without any further manual assignments.

Next is my A7V with the ATA100 and all the other goodies. .. now I have to determine how to gain access to device>resources>change settings to manually assign IRQ; for some reason its not giving me the option to select... I suspect it's some admin priviledge deal that I'm not familier with (this is the first time I've used NT). anyway thanks!!!
 
Sorry I forget to mention that - You've just removed the Advanced Configuration and Power Interface, this is also the interface that shuts down the computer. I don't know of any way around this, other than replacing ACPI and going back to having everything stuck on IRQ 9.
 
Assign IRQS through the bios now.. you are still going to have some shared ones as the mb shares IRQs with some PCI slots. Like my P3B-F actually only has one PCI slot that has an IRQ all by itself. Also and I think this is the best way to install Win2k without ACPI if you are going to do it is hit F7 during setup when it ask for F6 install of SCSI drivers.



***Hey I run Intel... but let's get real***
 
There is another downside to uninstalling acpi. I think you will find that your cpu idle temp will increase significantly (10c+). ACPI tells to cpu to throttle down when it is not being used.

Be careful if you are reinstalling acpi. When I tried win2000 wouldn't boot. I tried everything I could think of to get it back up but in the end I had to format the system drive.
 
I kinda thought that myself, but was hoping someone had a work around on it.
I can deal with that minor setback.considering all the potential i get with this os.
thank you for all your help cxg :)

OK all if you don't mind reading hear is some info and some links on ACPI (IRQ sharing)& how to switch or just set it up right in the first place (but what is right?):

and more info:

"Something else I found was that, when setting up the system, because I had only used one CPU in the Shuttle HOT-649A (a dual Slot 1 motherboard), Windows 2000 configured it as an MPS Uniprocessor PC rather than an MPS Multiprocessor PC type. In order to get full support for dual CPUs, I went into the Device Manager to change the computer type. While changing the type, I noticed that I wasn't currently using an ACPI-based Hardware Abstraction Layer (HAL), so I thought, "Why not kill two birds with one stone?" Big mistake: the system never booted all the way after that.
I searched the Microsoft Knowledge base, and found that it is strongly discouraged to switch from ACPI to non-ACPI or vice versa. They suggested that to do this change, run setup as an upgrade and have ACPI enabled or disabled in BIOS to get the proper files installed. This is because several drivers and services depend on whether or not the system kernel supports ACPI. If it does, then different versions of those drivers and services need to be installed. Because of the fact that simply changing the computer type does not switch driver or service files, it is not recommended to switch across the "ACPI barrier" without running setup.
In an attempt to recover, I booted to the Windows 2000 Setup CD and tried a repair without using the Emergency Repair disks. Selecting this option brings up the Windows 2000 Recovery Console. It sounds cool, but it's basically like booting to a Windows 98 Safe Mode Command Line. Most major DOS commands are supported, and using them, you can replace or edit whatever files you need to. When I discovered that, I was impressed that Microsoft added such a feature, but I realized how long it would take to recover the system and that I didn't want or need to spend that time attempting to recover a setup that would likely still have an overly-hungry svchost.exe. So from there, I just deleted the NTFS partition and started over from scratch. I went through a fresh install and everything worked as expected.
It is possible to skip all the mistakes I made with one simple change. The Microsoft Knowledge Base offers instructions describing how to change to a specific HAL during setup. By doing that, you can put yourself on the right foot from the outset of the installation."
