PCI IRQ/USB Conflict problem

[tomorrowman]

I am using an IBM PC 300GL 6563-83G as part of a digital studio set-up. The problem is I am getting serious audio drop-out which are only cured by removing the USB connected MIDI interface, which for obvious reasons isn't an option.

I have a clean installation of Win2K using "Standard PC" setting to disable ACPI in the OS. ACPI can't be disabled in BIOS.

USB Controller, video board and audio card are all reported as sharing IRQ 11. I want to ensure that the pci audio card gets its own IRQ. I had hoped disabling ACPI in the OS would permit me to do this, but I can't see how.

Any ideas?

Many thanks

go into your device manager....under your sound card...(maybe has a splash mark) ...go into the properties of it and there should be a resources tab.....take the check mark out of use auto config...manually hardset the irq of your choice...careful not to conflict with another device....this should cure the media blues...good luck...

Shadow - thanks for your reply.

If only life were that easy! The auto config option is greyed-out and I think this is because ACPI is hard-set in the BIOS.

I have solved the actual issue by buying a much more expensive but much better quality USB-connected MIDI interface which has a more predictable draw on system resources so even though the &quot;cause&quot; of the problem probably remains the symptom is gone.

But thanks for your thought all the same.
