I am trying to install a SATA drive as a secondary drive. The computer is trying to boot with the secondary drive instead of the master IDE drive. I need to boot with the IDE so I can read the SATA drive and make file corrections. Both drive have XP operating systems installed but the SATA has a corrupt hal.dll file. The SATA is from another computer. The computer with the IDE works fine except when I install the SATA. There are jumpers on the IDE drive. Can anyone tell me whast I need to do to make the computer boot with the IDE while recognizing the SATA drive as an addition drive?
