: I added the BIOS for you
I replaced the RSTe OROM 3.x.(DEV_ID_2826) with the TRIM X79 22.214.171.1246 OROM
In BIOS make sure to choose the RSTe option not the RST.
Step 1 - Delete the current array, then flash my BIOS
Step 2 - Shutdown the computer unplug the power cord for 5 min., Then CLR-CMOS
Step 3 - Turn the computer back on and re-setup your BIOS, Choose RSTe RAID mode, Make sure to Enable CSM (Legacy boot dont use UEFI boot).
Step 4 - Re-Setup your RAID array, then Install Windows 7/8/8.1, At the Windows setup screen choose Load Driver option, and point it to the USB stick that has the pre-install 12.8.x x64 driver, after that has been chosen install Windows as normal. (Edit: read Fernandos post below this post)
Step 5 - Once your in Windows Update the system threw Windows Update.
Step 6 - After its all Updated install the Intel Chipset drivers 126.96.36.1996, If on Windows 7 just run the chipset *.exe package to install them. If on Win8/8.1 youll need to update each device manually, For this youll need the extracted *.zip chipset package. Theres about 7 devices youll need to manually update, theres two USB, DRAM, PCI Express Root, SMBus, LPC controller, If your using the x1 PCI-E slots theyll be two more PCI Express ones above the SMBus.
Step 6 - After the Restart install the Intel RST Software package 12.8.x, This is to give you the RST GUI Manager and to enable Write Back caching.
Step 7 - Install rest of your drivers, I usually am strict on the driver install Order, 1>Chipset, 2>RST Package, 3>USB 3 drivers if applicable, 4>Network, 5> Intel MEI software, 6>Mouse drivers, 7>Sound Drivers, 8>Video drivers
