I am adding a second hard drive to my computer and I can't get the drive set up properly. I installed the drive, used the software that was provided by Maxtor for the 120gig ATA drive. the software found the drive but it's showing up as a secondary master. I'm getting an error message when I try ti install Windows XP. The message is; can't find NDLSR. How do I set the BIOS to make the new hard drive my primary master? It's showing my CD Rom as the primary master and my hard drive as the secondary master.
