Well not everything but way too much. Here is my main problem;

When I try using my ultra 160 drive it keeps rescanning the SCSI bus. This I am assuming is happening because I have an IRQ mess. Unfortunately Win2000 is allowing all the hardware to share IRQ 11!?!?! All I really want to do is find out how to change the IRQ's in Win2000 when it is allowed in the first place. (It seems when Win2000 sees that the IRQ's work, I can't change the configuration manually).
Here is my setup:
Win2000 - duh, I said that already
MSI K7T Pro2a - 1gig Tbird not OCed
3x Micron 128 megs single sided ram
AGP slot - CLAP
Slot 2 - Blank
Slot 3 - SBLive Value
Slot 4 - NIC
Slot 5 - Blank
Slot 6 - Adaptec 29160n
Slot 7 - Blank
The SBLive, USB, and Adaptec card are all running on IRQ 11. Do I have to disable the hardware to change the IRQ?

Move the SCSI card and SBlive card to different PCI slots.

Okay, first off it's NORMAL for Win2K to put everything on one IRQ. Only way to force Win2K not to is to disable ACPI Power Management in the BIOS menu. That will force Win2K to use the IRQs that BIOS assigns.

More than likely that's not your problem, though. I suspect you may have a PCI IRQ channel sharing problem (this is NOT the same as an IRQ conflict).

This problem is very common with NICs, some PCI sound cards (the SBLive in particular) and SCSI controller cards. These cards do NOT like to share a PCI IRQ channel (again this is NOT the same as an IRQ number - there's only 4 PCI IRQ channels, A thru D). I explain the problem in detail here with a fix: http://voodooextreme.com/flypenguin/glfaq5.htm#5_9

Since more than one card could be causing the problem, you'll be chasing your tail unless you troubleshoot it one card at a time.

<B>Make a note of which slot each PCI card is currently installed in right now.</B> Pull ALL your PCI cards except the video card and the SCSI controller and boot up. Make sure the system is working okay. If the system seems stable shut down and install ONE CARD AT A TIME IN THE ORIGINAL SLOT THEY OCCUPIED. Start with the sound card. Make sure that the sound card does NOT share an IRQ with any other device. If it does, or the system acts up, move the card to a different slot until it's resolved.

Repeat this process with all the PCI cards starting with NIC card next if there is one.

Hope this helps...

That's not the only way.

Device Manager -> Computer -> Update Driver
