W2K by standard puts your devices in ACPI mode and put them on very few IRQ's. It can be solved by switching to "standard pc". Here is an instruction from another guy. (Don't remember who it was, but a big thx to him)

<< It's ACPI ... Windows' power management control system. I'll tell you a way to have your IRQ's back, but prepare to have some install disks ready. It won't format, but all your hardware will be rescanned and reinstalled.Go to Control panel / System / Hardware. Click on &quot;Device Manager&quot;. Double click &quot;Computer&quot;, then right click &quot;Advanced Configuration blablabla&quot;. Go to Driver, then click on &quot;update driver&quot;. Click next. Select &quot;Display a list of blablabla&quot;. Wait. Click on &quot;Show all hardware...&quot;. Select Standard PC. Now just follow the steps. After you reboot, all your hardware will be rescaned and stuff. Some guy said that his Quake III performance doubled after this, mainly because his VGA card was sharing the same IRQ with sound/NIC/modem/usb stuff. >>

This is the way to do it when W2K is installed and you don't want to reinstall.

The best way to do this though, is to press F5 during setup where it asks you to press F6 for installing of extra drivers. This will allow you to choose &quot;standard pc&quot; from the beginning

PS: You could get the problem of the computer comming with the &quot;You can turn off your puter&quot; when you shut it down. This can be solved by installing the &quot;NT/APM legacy support&quot; (you have to show hidden devices to see it)

So what exactly what ACPI does for me that regular power management features don't? If I disable it will I still be able to have my hard drives and monitor power down after x minutes?

Thanks so much, I was looking just for that answer myself for a system I was helping a friend with, keeps freezing and it seems all his stuff is on irq 11 too, I'll try this now.

 

[Blayze]

all of my stuff is on IRQ 9
oh well it works. no problems, etc...

 

[Weyland]

I had a problem in Win2k where the video would go black after the login prompt. Turns out the modem and video card were trying to share the same IRQ. There was an option that turns off IRQ steering, can't remember where it was, but once I turned that off everything was fine. The system was set to Standard PC before hand also, but that didn't seem to fix my problem.

 

[BX|PHrEaK]

just an update.. I tryed reverting to standard PC like the second post said and indeed I had no conflicts. I also went from 170 frames per second in my quake 3 timedemo to 100. I tryed reverting to ASPCI or whatever and I ran into a crash upon boot problem. So I just reinstalled :/

anyone know other ways to manually set IRQs? in registry and such?

[cirrus1]

It is normally done in BIOS

Hey cirrus1,

I tried that switch to &quot;Standard PC&quot;, then got that problem w/ Shutdown not shutting down. I go back into device manager, viewed hidden devices, under the Non-Plug n Play driver, I don't see the &quot;NT/APM legacy Support&quot;. Anybody else have this problem? Please help if were able to solve this problem... it's getting to be a pain to have to pull out the plug to shutdown my system, and I don't wanna resort to a reinstallation yet...

 

[AndyHui]

If you switch from ACPI to standard PC, Win2K does not install APM support. That's why you won't see the legacy device and Win2K needs you to shutdown manually.

Go into Power Management and check if you have the APM tab anyway, and enable it if it is there.

Ideally you want to reinstall to get the Standard PC HAL initialised properly.

 

I switched to standard Pc a while back, and have GREATLY increased my systems performance and stability.
When it shuts down, all you have to do is hold in your power button for about 5 seconds, and the system will shut off.
Pulling the plug is not necessary.

 

[phlashphire]

Thanks for the quick responses!
That 5 second hold does work, but unfortunately I need my machine to be able to shutdown on it's own.
I went into control panel/power options/ and I don't see the APM tab anywhere... am I blind? Is there a way to install it if it's not present?

 

[cirrus1]

Yes there is.

Go in and install new hardware manually - say &quot;have disk&quot; - and under &quot;Legacy drivers&quot; or &quot;other devices&quot; you will find the NT/APM support. Install it and reboot.

BTW before installing it make sure that you have the ACPI driver disabled in &quot;other devices&quot; not uninstalled just disabled

 

[phlashphire]

Pardon my ignorance... I'm a little lost.
Can you be a little more clear w/ your instructions?
I go into Add/Remove Hardware Wizard, I select &quot;Add a new device&quot;, then &quot;No, I want to select the hardware...&quot; then &quot;Other Devices&quot;
I do not see anything such as &quot;Legacy drivers&quot;.
And by disabling the ACPI driver, are you referring to
the &quot;MS ACPI Driver&quot; w/in Non-Plug and Play Drivers in Device manager?
Thanks in advance.

Help?

 

[cirrus1]

I can't tell what excact to go into now since i'm at school, and we are running NT 4.0 here. I will post when I get back home.

 

[cirrus1]

ok here we go:

Open up Device manager... go to view... show hidden devices. Then open up Non-Plug and Play Devices... Find Microsoft ACPI Driver... DONT disable or uninstall that doesnt work. Go into Properties... then driver.... there is a pull down menu to tell windows when to start this driver... Set it Disabled.... Reboot and go back into it.... the driver will still be there and thats ok... go back into properties and where it says status make sure it says Unavailable. After that you need to install a new driver... manually go in and add NT APM/Legacy Support... It will install something called NT APM/Legacy Interface Node.... reboot and everything should be all good. BTW you can NOT install the NT APM/Legacy if the Microsoft APCI driver is running.

Good luck

 

[phlashphire]

Hmm... it's not working the way as described..
I did everything up to the point of &quot;manually go in and add NT APM/Legacy Support&quot;
That's the part I was having problems with before. And when you say &quot;manually go in..&quot; what exactly are you referring to? I do not see the &quot;NT APM/Legacy Support&quot; within Non-Plug and Play. And I also checked that the ACPI was disabled correctly.
I've read several threads in regards to this subject, and the solutions are basically similar. I must be missing a step somewhere? I guess the only solution is to reinstall and have it set as APM from the start... Thanks again cirrus.

 

[cirrus1]

Ok i'll try again:

Hardware Wizard - Add/troubleshoot - mark &quot;add device&quot; next - no I want to select from a list - NT Apm/Legacy support next - next then it will install it

 

[mariner]

phlashphire, have you solved your problem? Did you get cirrus1's solution to work?

Good detail cirrus1!!

 

[phlashphire]

Well, I gotta thanks cirrus for helping but unfortuanately it didn't work...

This is exactly what I'm doing -but it's still not working.
1. Check to make sure MS ACPI status is unavailable.
2. Go into Hardware Wizard, Add/Troubleshoot.
-marked &quot;Add a new device&quot; among list of hardware devices.
3. Mark -&quot;No, I want to select the hardware from a list&quot;
4. There is no &quot;NT APM/Legacy Support&quot;!
this is what I do have...
Batteries
Display adapters
IDE ATA/ATAPI controllers
IEEE 1394 Bus host
Imaging serv.
Infrared dev.
Memory tech. drv.
Modems
Multi-port adptrs.
Network adptrs.
Other devices
PCMCIA adptr
Ports (COM&amp;LPT)
Printers
SCSI and RAID contrl
Sound video, and game ctrl.
System devices
Tape drives

The first place I then look in was the &quot;Other Devices&quot;
and I don't see anything relating to APM in there either...


Am I doing anything wrong? Maybe my system just don't have support for APM? Is it something I have to do w/in the BIOS?


I also searched in dropdown menus in device manager and select &quot;show hidden devices&quot;. Still don't see NT/APM.

 

[GAZZA]

Funny you mention installing the NT APM/Legacy Support as i have just done this not 10 minutes ago on afriends pc.
goto add/remove hardware .add trouble shoot device.hit next one it has attempted to find any plug and play devices then click ADD NEW DEVICE and then click NO I WANT TO SELECT THE HARDWARE FROM A LIST and then select NT APM/Legacy Support from the list and away you go

 

[phlashphire]

I did exactly what you described GAZZA...
there is no selection &quot;NT APM/Legacy&quot; on the list, as stated on my previous post. Thanks for trying to help.
Is there any other way to verified that NT APM/Legacy has been installed? Since it's not on the list of installable hardware, I'm assuming that it was somehow installed already(?).

 

[GAZZA]

the only way to find out if it is installed is to goto the device manager and view hidden devices and you should see it listed.
