4 Intel Rapid Storage Technology (IRST)
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 the 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: If a SATA hard drive is already installed, enabling the
RAID controller might cause your computer to display a blue screen
and an error code followed by a system reboot. To enable RAID,
reinstall the operating system.
