Legacy hotkey combinations cannot access the Basic Input/Output System (BIOS) Redundant Arrays of Inexpensive Disks Controller (RAID) controller configuration Read-Only Memory (ROM). Where the BIOS is configured for Unified Extensible Firmware Interface (UEFI) boot mode on Precision, OptiPlex, Alienware, and other Dell computers. Learn how to launch and manage RAID Arrays through this article.
Where Precision, OptiPlex, Alienware, or other Dell products with RAID controllers are configured for UEFI boot mode, it affects the hotkeys. Because of this configuration, the RAID setup utility built into the BIOS does not open using CTRL + I, CTRL + H, or other hotkey combinations.
The hotkey access to the RAID setup functions only when the BIOS is configured for the Legacy boot mode.
In most cases, RAID can be managed from the Intel Rapid Storage Technology (IRST) user interface (For Example) inside Windows. If you cannot manage the RAID array in Windows, you should access the RAID configuration from the UEFI BIOS F12 Device Configuration menu.
The RAID setup utility runs and allows for configuration of the computer’s RAID array. See Figures 2-19 for examples of the Intel Integrated RAID in UEFI mode. Intel Integrated RAID can be configured from either the Intel Rapid Storage Technology (IRST) user interface or from the RAID BIOS.
Below are examples of the IRST User Interface (UI) and the UEFI BIOS during the configuration of Intel Integrated RAID. Other RAID controllers may have different screens, but the basic configuration functionality should be similar.
Recovery Array
The IRST user interface allows you to create RAID array configurations from within the operating system with ease.
- Creating a Recovery Array (Default) using the Intel Integrated RAID controller and the Intel Rapid Storage Technology user interface. (See Figure 1.)
Figure 1. The first step in creating a Recovery RAID Array
- Select the type of RAID array that you want to create. (See Figure 2.)
Figure 2. RAID array selection choices
- Configure the selected drives in the RAID array. (See Figure 3.)
Figure 3. Selection of the disk assignments in the Recovery array.
- Confirm the creation of the recovery volume. (See Figure 4.)
Figure 4. Creation of the Recovery volume array.
- Click OK on the volume creation complete. (See Figure 5.)
Figure 5. Recovery Volume array creation completes.
NOTE: After the array is created, you are prompted to open Disk Management to create and format partitions on the array.

When these computers are configured in UEFI BIOS mode, the RAID setup is accessed from the F12 preboot menu.
Press F12 on power up while at the Dell logo splash screen. Then, select "Device Configuration" from the list shown in the F12 preboot menu. (See Figure 6.)

- Creating a RAID 1 Array (Mirror) using the Intel Integrated RAID controller and the Intel Rapid Storage Technology user interface. (See Figure 7.)
Figure 7. Creating a RAID 1 Array (Mirror).
- Select the drives to create the RAID array. (See Figure 8.)
Figure 8. RAID 1 (Mirror) drive selection.
- There is an optional selection of the size of the RAID 1 array (Default is 100%). (See Figure 9.)
Figure 9. Selection of the size of the RAID 1 array.
- Confirm the RAID 1 Volume. (See Figure 10.)
Figure 10. Confirmation of the RAID 1 Volume.
- The volume creation finishes. (See Figure 11.)

You can also create RAID volumes in the UEFI RAID BIOS that you access from the F12 Device configuration menu (See Figure 6 above.)
- Once you select Device Configuration and press the "Enter" key, you are presented with the RAID status page. To create a RAID array, ensure "Create RAID Volume" is highlighted (using the array keys) then press the "Enter" key to start the array creation process. (See Figure 12.)
Figure 12. Create RAID Volume.
- In this configuration, we change from the Default RAID 1(Mirror) to the RAID 0(Stripe) option using the "+" Key. (See Figure 13.)
Figure 13. Changing from the default RAID 1 to RAID 0 striped array.
- Once you have selected your array type, you then must select the drives to be configured in the array. Use the arrow keys to highlight the drive, then press the "Enter" key to select the drive to add. (See Figure 14.)
Figure 14. Selecting the first drive to add to the array.
- An on-screen box appears for the drive, use the arrow key to highlight the selection space, type an "X" to select then press the "Enter" key to complete the drive selection. (See Figure 15.)
Figure 15. The drive selection screen.
- Repeat the selection process for the second, third, or even fourth drive (Depending on drive and chassis configuration) (See Figure 16.)
Figure 16. Selection of the second drive for the array.
- Use the arrow keys to go to the "Create Volume" option that becomes available once there are at least two drives selected. (See Figure 17.)
Figure 17. Creation of the Volume after drive selection is completed.
- Once the Array is complete, you can see the status of the array. (See Figure 18.)
Figure 18. Array status after array completion.

If an array already exists, there is an option available to delete the array. When the delete option is selected, you must confirm the array deletion, and you receive a warning that the Volume is being wiped. (See Figure 19. Below.)
