On the original BIOS of the SR2 motherboard, it was necessary to update the BIOS to version A46 or later. There was a issue with the Matrix storage manager showing up when the e-SATA was enabled.

The latest bios is available from: www.EVGA.com/drivers It will be listed as "W555 - Classified SR2 bios"
