IRQ sharing question in Win 2k

[Vas_Deferens]

I have 2 NIC cards and my video adapter sharing IRQ 9, as well as a sound card driver and a USB host controller. Does this seem like too many items for 1 IRQ to share? I don't have any conflicts, and maybe I should leave it alone, but does anyone have any input on this? Thanks.

you should leave it alone. its normal. the cause of it is acpi. i thought it wasnt normal, so i disabled acpi and everything died. although people have done it without anything going wrong, dont disable it without.. backing up. =_

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.

If you have no problems, I recommend you leaving the assignments alone.

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.

You may lose the ability for Win2K to shut down properly by itself. If this is the case, you will need to disable the ACPI driver and install the APM driver. I recommend doing a reinstall for full system support.

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.
