The IRST software package enables and enhances high-performance Serial ATA (SATA) and SATA RAID capabilities for supported operating systems. The IRST software package provides an added protection against data loss in an event of a hard drive failure.
NOTE: The following conditions must be met before you can install IRST on your computer:
Your computer has a RAID I/O controller hub (ICH). If your computer does not have a RAID ICH, you cannot install IRST unless a third-party RAID controller card is installed.
Your RAID controller is enabled by default.
CAUTION: Enabling the RAID controller with SATA hard drive preinstalled might cause your computer to display a blue screen with an error code and a system reboot. To enable RAID, reinstall the operating system.
