environment. For information about configuring RAID in the Linux environment, contact your Linux software
provider.
This chapter provides information about the following topics:
• "Configuring RAID with Intel RSTe" on page 44
• "Quick RAID setup using the LSI MegaRAID BIOS configuration utility " on page 47

Configuring RAID with Intel RSTe

If 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:
