Flashing a SAS controller to IT Mode configures the SAS controller to provide the operating system with direct access to each of the attached drives; instead of a single RAID device managed by proprietary software. Using IT Mode provides greater flexibility, manageability, and portability. Tools are provided to build a FreeDOS USB image that comes bundled with the necessary software and helpful scripts to switch your SAS controller over to "IT Mode".
