ATI RADEON 9000/9001 IGP video chipset. Symptoms are consistent click and pops during audio playback. This video chipset is only found in PC laptops and is entirely integrated as the computer’s only video controller. We strongly recommend that you do not get a system with this chipset, as there is currently no workaround for this incompatibility.
USB/firewire and s400/s800 combo cards are not compatible. Symptoms are usually no audio recording/playback but device will install and sync, erratic audio performance and rarely will not allow the device to install or sync. We recommend a firewire card that ONLY has s400 firewire connections and preferably with a Texas Instruments or VIA chipset.
Firewire cards with NEC chipsets are not compatible. Symptoms are similar or the same as combo cards.
Motherboards with nForce4 chipsets. Symptoms include reduced to very poor performance especially if using the onboard firewire connection. A PCIe (not PCI) FW400 only card with a Texas Instruments chipset is a known workaround, but may not allow full performance.
