3-28 Configuring RAID Using the Basic Input/Output System (BIOS)
Marvell RAID Utility User Guide
3.1 Accessing the BIOS
The main BIOS configuration screen displays three main functions, a set of keyboard
commands, and configuration information about the physical disk drives and the logical
drives, if any.
The functions are:
 Adapter. Displays the physical drives installed on your computer.
 Create. Lets the user create logical drives.
 Delete. Lets the user delete an existing logical drive.
The keyboard commands are:
 Arrow keys. Use the arrow keys to navigate the screens.
 ENTER/SPACE. Use these keys to select an item and execute a command.
 ESC. Use the escape key to go back one screen or exit the program.
The configuration information for the physical and logical drives are:
 ID. This displays the identification number assigned to each logical drive by the BIOS.
 Level. This displays the RAID level configuration of the logical drive.
 Size. This displays the data capacity of the logical drive in Megabytes (MB).
 Members. This displays the disks that are included in a logical drive.
 Status. This displays one of the following logical drive conditions:
 Online: The logical drive is functioning at the optimal level.
 Degraded: The logical drive is functional but does not perform fault tolerance. For RAID
levels 1 and 10, the logical drive contains a drive that has stopped functioning. If set to
auto-rebuild, the logical drive rebuilds itself on the spare drive, if available on your
computer. Identify and replace the failed disk drive.
 Offline: The logical drive is not functional and cannot be rebuilt. Therefore, replace the
failed drive and create a new logical drive to copy over your data.
To access the MRU through the BIOS
1. Reboot your computer.
2. Before Windows starts, press CTRL+M to enter the BIOS, as shown in Figure 3-1.
