The answer about disabling the SATA ACHI was the correct one!
Worked for me, and thanks a lot to the guy that posted it---you also have to disable some type of "FLASH"
switch, but whenever I went to change the SATA settings as directed, it prompted and told me to do that also, and now it sees my hard drive (SATA, of course....) But you saved me alot of grief, so thanx!
