IT Mode

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. Tools are provided to build a FreeDOS USB image that comes bundled with the necessary tools and helpful scripts to switch your SAS controller over to "IT Mode".

Preparing the FreeDOS Image

Debian Dependencies

apt install curl p7zip mtools

Prepare the image

git clone https://git.15h.org/rane/itmode.git
cd itmode
