Then,disconnect all power cords from electrical outlets and disconnect all cables that are connected to thecomputer.2. Remove the computer cover. See Chapter 9 “Installing or replacing hardware” on page 99.3. Locate the Clear CMOS /Recovery jumper on the system board. See “Hardware locations” on page 27.4. Remove any parts and cables that impede your access to the Clear CMOS /Recovery jumper.5. Move the jumper from the standard position (pin 1 and pin 2) to the maintenance position (pin 2 andpin 3).6. Reinstall the parts and cables that were removed.7. Reinstall the computer cover and reconnect any cables that were disconnected. See Chapter 9“Installing or replacing hardware” on page 99.8. Turn on the computer and insert the BIOS update disc into the optical drive. Wait a few minutes. Therecovery process begins. After the recovery process is completed, your computer will shut downautomatically.Note: If the computer does not start up from the disc, select the disc as the startup device.

Then, turn on your computer.Configuring RAIDThis chapter provides instructions on how to install hard disk drives and configure RAID for yourcomputer. Depending on your computer model, RAID can be enabled by Intel Rapid Storage Technologyenterprise (RSTe) or the LSI MegaRAID BIOS.Note: The RAID configuration information described in this chapter is only applicable in the Windowsenvironment. For information about configuring RAID in the Linux® environment, contact your Linuxsoftware provider.This chapter provides information about the following topics:• “Configuring RAID with Intel RSTe” on page 71• “Quick RAID setup using the LSI MegaRAID BIOS configuration utility ” on page 74Configuring RAID with Intel RSTeIf your computer comes with Intel RSTe, you can follow the sections below to configure RAID with Intel RSTe.This section provides information about the following topics:• “Installing SATA or SAS hard disk drives” on page 71• “Configuring SATA or SAS RAID functionality with the Intel RSTe configuration utility” on page 72Installing SATA or SAS hard disk drivesEnsure that your computer has the minimum number of SATA or SAS hard disk drives installed for thefollowing supported levels of RAID:• RAID Level 0 - Striped disk arrayChapter 6.
