Ok not the aspi drivers!! This has to do with the way xp configures your system during the installation of the software. so you'll have to wipe the drive and reinstall xp. ACPI is a totally different thing. And to "hardset" your irq settings for your motu you'll have to take note of which slot you throw it in then press delete as soon as the computer starts to drop into the bios. It's usually under the pci configuration menu.
hope this helps
