The SiI3132 is a PCI express Serial ATA controller. Serial ATA controllers are responsible for managing information flow and connections between hard disks and optical discs. The SiI3132 comes equipped with a 4 megabyte flash memory area that contains the system BIOS. You can update your SIL3132 BIOS by flashing this storage area with a newer version. New BIOS updates can contain enhancements in efficiency, stability and drive support.
Download the latest version of the SIL3132 BIOS Update Utility from the Silicon Image website to your desktop.
Double-click "SiFlashTool.zip" to open it in Windows Explorer, then click "Extract All Files."
