LSI Embedded MegaRAID Driver

The LSI Embedded MegaRAID driver from LSI Logic enables Windows to communicate with the system’s embedded RAID storage controller and access drives configured through it. Selecting a compatible driver helps Windows recognize the storage volumes used for your operating system and data.

Key Features

• Storage controller recognition: Identifies compatible LSI Embedded MegaRAID hardware so Windows can communicate with the controller.
• RAID volume access: Allows the operating system to use logical drives created through the controller’s RAID configuration utility.
• Windows storage integration: Connects supported controller hardware to the Windows storage stack for disk read and write operations.
• Installation and recovery support: A compatible extracted driver can help Windows Setup detect a RAID volume when the controller is not recognized automatically.

How to Install

1. Confirm your hardware and Windows version. Check the controller name in Device Manager or your computer’s documentation. For Windows 11, 10, 8, or 7, verify that the download explicitly supports your OS version, system architecture, and controller hardware ID. Compatibility can vary between embedded implementations.

1. Download and extract the appropriate package. Prefer a driver validated for your computer or motherboard model. Extract the files to an accessible folder; if you are installing Windows, copy the extracted driver folder to a USB drive.

1. Prepare before making changes. Back up important files and note your existing storage configuration. Do not change the BIOS storage mode or recreate RAID arrays simply to install a driver, as doing so can prevent Windows from starting or put data at risk.

1. Install the driver. Run the supplied installer if one is included. Otherwise, open Device Manager, locate the controller, select Update driver, and browse to the extracted folder. During a fresh Windows installation, choose Load driver at the disk-selection screen and select the compatible driver from your USB drive.

1. Restart and verify operation. Reboot if prompted, then check Device Manager for controller warnings and confirm that your expected volumes are accessible. If Windows rejects the package or reports a compatibility issue, obtain a supported version rather than forcing installation.

The driver provides controller access; RAID creation, monitoring, and advanced management may require separate firmware utilities or management software supplied for your system.
