Sharing IRQ's?

[CMO23]

hi guys, i recently just switched over to win2000 pro from win98, and am still trying to get used to it. i noticed that all my peripheals are sharing the same IRQ (sound card, video card, scsi controller, modem, and ACPI)... however, none of them display any conflicts. is this normal in win2000? and what is ACPI for?
the only problem i notice is that i cant put my sys on standby (error:"SCSI card is preventing sys from going on standby&quot😉... i only noticed this error after i installed the SP-1. thanks in advance for any helpful info guys =P

Here we go again....a copy and paste from my other responses:

Windows 2000 has been installed in ACPI mode and that is how it assigns its plug and play resources. Most people have no problems, other people do have problems. Usually it's all assigned to IRQ9...supposedly it's used as a gateway to virtual IRQs above 15.

Anyway, here is the article from Microsoft dealing with it.

If you want to manually assign IRQs, or just let Windows do it properly, you have to change the ACPI mode HAL to Standard PC HAL.

To do this, go into Device Manager, and look under Computer. It should say Advanced Configuration Power Interface PC. Change this to Standard PC by changing the driver. Then reboot. Hopefully it should come out OK.

If you need to reinstall, hit F5 while it is detecting all the devices right at the very beginning to manually select the Standard PC HAL. You may also need to turn ACPI off in the BIOS if you have that option.

Thanks AndyHui! =P

sorry for askin' a question that had already been discussed... i tried using the search engine for this forum but nothing came up.. thats why i posted a new thread...

anyhow, i changed my driver settings to Standard PC like you said, and windows did assign a unique IRQ for my sound/video card (my modem and SCSI still share)... however, the PROBLEM NOW is that i no longer have the option to go on standby... AND my sys no longer powers down automatically... i get a 'it is now safe to turn off your computer' message, and my power switch doesnt even work! i have to reset and just turn off the power before it boots up! does anyone have any idea whats goin on?!@!?

Ah....that's the problem with not properly installing with the Standard PC HAL in the first place. No support for APM.

You need to add APM support. Go to Add New Hardware, click Add New Device after it has finished detecting Plug+Play devices, then select NT APM/Legacy Support from the Hardware List.

Reboot, go to the Power Options Applet in the Control Panel and then enable APM.

hey AndyHui,

i installed the 'NT APM/Legacy Support'.... however, i dont see anything about APM in the Power Options.... is there anything else i was supppose to turn on/off? is there anything in my BIOS that im suppose to change? APM is enabled in BIOS... i dont have an option to 'turn off' ACPI in my BIOS, just different settings: S1 or S3.. ill try looking that up in my manual...
but anyways, thanks any more info you might have for me.... i appreciate your patience =P

Before you can install the NT/APM legacy support the Microsoft ACPI driver must be disabled. To do this go into device manager and say "show hidden devices". Under "Non PnP drivers you will properly find the Microsoft ACPI thing. Disable it (don't uninstall it, that won't work) - reboot - go into device manager again and enable the NT/APM legacy support which you installed (or install it again). Voila!

Edit: If you still got trouble, please keep in touch 🙂

hey guys...

thanks for the additional info... however, im sorry to say that i still coulnt get my APM working w/out ASPI... when i went to enable the NT/APM legacy, it gave me the exclamation error, drivers missing/not installed properly. i dunno... i just switched back to ASPI, at least my sys can shut down again now =P
