Creating RAID arrays in the EFI shell

Supported configurations

When booting to a GPT RAID partition it is necessary to first create the RAID array. The boot array, in addition to data volumes, can

be created using tools in the EFI shell prior to booting from the install media.

• GPT is currently supported by Win7-64 only

• Storage controllers must be configured to use the EFI driver.

• Controllers:

• Z420/Z620: Intel C602 AHCI and SCU controllers

• Z820: Intel C602 AHCI and SCU controllers, LSI 2308 controller.

Enabling the EFI Drivers

Use the following procedure to enable the EFI driver pre-OS for the different storage controllers.

Note: These instructions are for v02.07 BIOS. In earlier BIOS versions, the controller settings might be listed separately.

1. Press <F10> to enter the BIOS setup menu.

2. On the Main menu of the BIOS-based configuration utility, navigate to the Advanced menu item using the arrow keys.

3. Navigate to the sub menu item Device Options using the arrow keys and press Enter to access the Device Options menu

screen.

4. On the Device Options screen, navigate to the Mass Storage Option ROMS item using the arrow keys.

5. Use the right or left arrow keys to change the selection from Legacy to EFI.

Press <F10> twice to go back to the File menu and make sure Save Changes and Exit is highlighted.

7. Press Enter to bring up the Save Changes and Exit confirmation. Make sure Yes is selected and press Enter. The

system will reboot.

Creating a bootable UEFI USB key A BSD licensed x64 UEFI shell can be downloaded from the Intel Tianocore EDK2 project on Sourceforge.net. https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2/EdkShellBinPkg/FullShell/X64/Shell_Full.efi 1. Create the following path in the root of the USB key: \EFI\boot 2. Place the downloaded .efi shell file in the \EFI\boot folder named as: bootx64.efi 3. Copy the following files to the root folder of the USB key: RCfgSata.efi (For Intel AHCI controller) RCfgScu.
