Running XP on a VIA VB7001 Mini-ITX Board (specs http://www.via.com.tw/en/products/mainboards/motherboards.jsp?motherboard_id=490)

I have two PCI slots, and the plan is to run this board with a Delta1010LT in both. I have custom software using ASIO drivers. Everything works great on my dev box (standard Dell server), but I've moved the two cards and the application over to the VIA Mini box and I'm having problems. As soon as I start the app, it gives me a blue screen with the problem being delta.sys and IRQ. Doesn't put anything in the Event Log so that's all I have. I've noticed that one card is on IRQ 17, and that's fine. The other card is on IRQ 16 which is being shared with the video driver and I'm thinking that can't be good. So I disabled the Delta driver on IRQ 16, and the app runs.

I don't think I can change the IRQ, but I still wanted to get any expertise from the forum. Maybe there's other drivers I can use?

Unfortunately we've seen problems like these with shuttle PC's and VIA chipsets. The conflict with the video is what's causing the crash. Have you checked in the BIOS for any plug n play settings or anything that may allow you to change IRQ's?

Thanks, JA.

I'm in the process of trying to change the IRQ, but it doesn't seem possible. One thing I did notice is, I disabled the Via S3 graphics driver that was using the same IRQ 16 as one of the Deltas. When I rebooted, windows showed that only the Delta was using 16. When I tried running our application again, it didn't help. Same blue screen. So I'm wondering if changing the IRQ will even help. Once I get in contact with the board manufacturer I'll have more answers.
Thanks.

I see, another with blue screen problems with Delta 1010lt just like me.. Unresolved.

Not sure if it'll be any help, but I found most problems went away if you didn't install the VIA 4-in-1 / Hyperion driver. It's a pig. Unfortunately, once you've installed these drivers you'll probably have to reformat your system to completely remove them because the VIA uninstaller doesn't work properly.

Also, because of the way Windows handles IRQs, you may have to move them all around in the Windows Device Manager rather than in the BIOS.

Your other option is to get a 3-way riser, and use a PCI graphics card (I recommend nVidia cards, because they don't require any runtime IRQs) but you risk saturating the PCI bus with graphics and audio on one riser.

It might be worth considering a different board/CPU, if you need to resolve the problem quickly.
