I was trying to install windows 2003 on my portable after I uninstalled vista from it. When I ran setup it didn’t find any harddisks. Not kowing that this portable has got a SATA Hd I tried dozens of tricks to get the thing going, but none were succesful. Finally a couple of hours later I read on a forum that the little bastard has got a bios setting called SATA Native Mode and that I should set that to disabled. When I did this everyhting was fine and I could install my other OS.
