The new Intel RST(e) drivers of the v12 series are mainly designed for the upcoming Intel 8-Series Chipsets and do not support any Intel ICH7/8/9/10 SATA Controller.
Which is the chipset of your system? Lower than 5-Series cannot use the original Intel RST(e) drivers v12.x.x.xxxx, because the needed HardwareIDs are missing within the INF files.
