win2k advice need regarding IRQ 9 -ACID Product Family

Subject:win2k advice need regarding IRQ 9 Posted by: CDM Date:9/22/2001 12:12:27 PM I finally have dedicated my system to win2k instead of the multiple boot hell I used to have. So, I really want to make sure my system is running optimally however I noticed right away that, although it claims no conflicts, just about every piece of hardware I have is sharing IRQ 9. Is this bad and if so, how do I change it? I can't imagine that having my network card, my firewire card, my Delta1010 and my SCSI card all sharing the same IRQ isn't causing performance slowdowns. any advice would be appreciated. Charles.

But what you could try to do is remove all cards, and reinstall them one at a time and do a few restarts between each install so Windows writes new files to boot everytime, and check IRQ's after each card install. Also change the slot config, See if you can find out which PCI slot shares with AGP if you have one, and use that for your Modem. If you have a Via Chipset get the latest drivers "4in1" for it, and install them also. Well you have your work cut out for you. Good luck See ya, Rockit

There is nothing technically wrong with doing this. It does assume that all drivers and hardware are designed and implemented correctly. Sharing IRQs on the PCI bus is defined by the PCI specification. Problems arise when the hardware or the drivers don't implement with this in mind. There is a solution if you are seeing problems. It involves switching the kernel that Win2000 uses and should be done on a fresh install of Win2000. (Some do it after the install, but this is not recommended by MS.) One of the simplest ways to try this - assuming this is the problem - is to go into your BIOS and disable ACPI on your mobo. When you restart Win2000 it "should" detect the change. If things don't work, just set your BIOS back to the way it was, and your Win2000 installation should be fine. Peter
