I have the 955x express chipset. I installed this Intel Matrix Storage Manager, that I suppose updates underlying drivers but I didn't check. I ended up with a windows app (the Manager) that showed I had 2 disk drives. It didn't appear to have any other functionality. The dropouts weren't fixed.
Another Intel download is the floppy for a clean windows install, if you need the storage driver for the f6 driver option. I was considering doing a clean install to see if I could get the 1394 controller on it's own interrupt. I have 3 major devices on IRQ 19: usb, sata, and 1394. But am very likely to end up in the same situation if I reinstall windows. The best alternative may be to give up on the onboard 1394 and use a plugin 1394 card. > Just an FYI for those running the PreSonus Firebox with mother boards > equipped with specific Intel chipsets, PreSonus has recommended the > following driver update to resolve a potential intermittent audio > dropout/glitch condition during playback.
