A customer requested I setup their DAW system based on the above article. However when I do, the PCI based cards do not work. They show up and the drivers are loaded by XP but they have an exclamation mark and the message "This device cannot start" - Code 10. Switching the cards around makes no difference. I reinstalled XP the standard way and all the items were recognized and work without a hitch. The mainboard is a Asus A7M266 with dual MP1800 CPU's, Matrox G450 32MB Dualhead video, Dakota soundcard, USB 2.0 PCI card, 3Com 10/100 network card, 1GB of memory, dual 80GB harddrives. At this point XP has been installed and the mainboard AGP and IDE drivers. No Windows updates as yet have been installed. Anyone with any ideas on this? Must have something to do with setting XP up as a "standard pc". Btw - the article is pretty in depth but an area on BIOS settings and which XP updates to install would be useful. Thanks for any help!
