IRQs above 15?

[liquorboy]

After purchasing my new cable modem I noticed that the NIC card was running on IRQ 17. During the installation of the software need to online it prompted saying that I did not have a NIC card in the system when I have been using the same one for awhile on my home network. I have since tried 3 different cards and three separate brands (3com, netgear, intel) and none will work. All seem to hook IRQs above 15 which will not work with the configuration of the modem.

I tried to go into my system bios to reset the IRQs for each pci slot and assign them to free IRQs between 0-15, but the system reverts back to the 15+ settings. I do not know how to get the IRQ between the accepted range so that I can use my cable modem. Any help would be great. I've included a few links that I've found regarding this issue.

Wrong forum.

You need to disable ACPI to force 'legacy' use of IRQs.

No you don't. There is also a pre-ACPI method for BIOS to describe the "advanced" interrupt routing to the operating system, and Windows can also handle that.

What you need to do is force the Windows installation to use a legacy "Standard PC" hardware abstraction rather than "ACPI Uniprocessor PC" or "MPS Uniprocessor PC". AFAIR you can do that after installing, by choosing a different driver for the root node in your Device Manager's "Devices by connection" view.

Or just kick your cable modem supplier's ass until they provide WORKING drivers.

Despite having dual cpus I can still choose "standard pc."

Will this affect my multiprocessor support at all?
