On the MSI P7N motherboard, the onboard raid must be disabled to gain enough resources to load the TX4660 BIOS in memory.

The FastTrak TX-4660 BIOS won't run properly unless the on-board 8 port USB controllers are disabled.

The installation of a third party 4 ports USB 2.0 controller in a PCI slot seems not to affect the FastTrak TX4660 functionality.
