A question to ASUS A8N-SLI Deluxe owners

[STi]

If you have an Asus A8N-SLI can you tell me what IRQ windows has assigned your display adapter?

I need this information because my setup has assigned the display adapter IRQ at 18. According to BFG this is not good. I have had issues with booting up, once I get to XP the screen goes blank or shows a colored noise pattern. I think the vid card is toast but BFG wants me to change the IRQ first. Anyone who has tried to change the IRQ settings with XP knows this isn't something you do easily.

Anyway I just wanted to get some sample information from people who have everything working to help figure all this out.

Mine is IRQ 18 too. No stability problems.

My Leadtek 6600GT is also on IRQ 18.
Absolutely no problems at all in 3 weeks.
I think BFG is full of shiite.

You won't be able to change to IRQ setting unless XP/2000 is running the Standard PC Hardware Abstraction Layer. You can set it in the BIOS all day but XP/2000 will assign whatever IRQ it wants unless you change the HAL. And changing the HAL isn't recommended once you are in Windows. It should be done during installation.

I agree, changing the IRQ assignments is a nightmare and not something I want to do. BFG is recommending I do this, but I don't understand the logic behind it. The only problems I have seen with IRQs is if they are shared, typically the sound card with the video card. That certainly isn't the case here.

I have seen the instructions for changing the HAL and ACPI configurations and those don't seem like valid solutions to my problem considering they would take my computer back to the stone age of BIOS controlled IRQ assignments.

My primary goal here is to show BFG that there are plenty of people running in this configuration just fine.

Actually the BIOS will assign the IRQ's instead of Windows. You don't have to set them. I leave it set at AUTO unless I have a conflict.

This may be true initially when the BIOS is going through the startup procedure but once windows takes over the IRQ assignments are controlled by XP. This is what the ACPI setting is for, it allows for Plug and Play devices to get an IRQ assigned without restarting the computer. At least that is how I understand it.

I wonder if the IRQ 18 assignment is common for PCI express motherboards?
