Thanks for you offer to help. I got it installed in the mean time though, via. 1.Download floppy version of intel matrix. 2.Extract the drivers to a floppy then to a map on your disc. 3.Update the IDE/SATA driver to Intel 82801GR/GH SATA AHCI from the extracted floppy. 4.Reboot and enter BIOS and set the IDE to AHCI.Save and exit.Now windows will boot and find a new hardware and will reboot again. 5.Install Intel Matrix Storage Manager latest (CD version) and reboot. I'll have to wait for my sata hdd returing from rma to do some benchmarking.
