Hi I've just got myself a new sound card but it's fitted in on an IRQ channel with 2 other PCI devices and I think that this must be the reason that since installing it my PC is hanging on a black screen during start up for about 3 minutes, just after the windows splash screen.

Could someone please let me know how to change the IRQ settings (if this is indeed what I need to do) through the BIOS as I can't do it in windows (something to do with ACPI I beleive).

Thanks very much for your time.....

Theo, London

Hi

You're right about ACPI being the reason you cannot change the IRQ in windows. Unfortunately, ACPI also means that you can't change it in the bios usually either. The main reason being is that ACPI overrides the bios settings most of the time.

Your best chance at changing the IRQ assigned to the sound card, is to move the card to a different PCI slot.

Whether this will solve the boot up problem or not, I couldn't say for sure but it's certainly worth a try.

Someone on another forum pointed out that changing the PCI slot is the easiest way to change the IRQ value. Unfortunately the Trust card effectively uses 2 slots so this is not possible.

Perhaps someone knows of a DOS program for changing IRQ slots?

Just had a look at the sound card - I see what you mean about two slots.

How many PCI slots do you have in total & which slots are occupied by which pci devices?
