Ok, i just bought a new Samsung sata drive (Sata II, 160GB, 8mb cache) for my old pc (p4, Asrock board) but now i want to install xp but the bios doesnt find the hard drive. The board HAS sata but its only sata I. The hdd manual says that some sata I host boards can not connect to some hard drives, and, that this is the case, i should switch it to sata I mode which i cant do because it doesnt come with jumpers (has the places but not the jumper). It says i can do it with a software which i cant find. Help guys.
