I have Gigabyte GA-X38-DQ6 motherboard with ICH9R 6 port sata controller.
Latest was 10.8.0.1003 version driver witch contaning ICH9R, but this is very old 10/17/2011 driver.
Where can i download latest Intel RST F6 preinstall driver witch contaning ICH9R support?
Intel's official RST driver iaStor.sys v188.8.131.526 definitively works fine with ICH8R and ICH9R systems running in AHCI mode, but the required HardwareIDs are missing within the associated text files named TXTSETUP.OEM and iaAHCI.inf delivered by Intel.
You should ask Intel why they did not add the DeviceID of your "Intel(R) ICH9R/DO/DH SATA AHCI Controller".
