I have 2 existing EIDE HD’s. I just bought a SATA HD. Can SATA HD be used..

I have 2 existing EIDE HD’s. I just bought a SATA HD. How do I use the new SATA HD as my master boot HD and the old EIDE HDs as my storage drives? I’ve already copied everything from my master EIDE HD to the new SATA HD and everything is plugged in. When I boot up the system, it is still booting from the old EIDE HD and the new SATA HD is being used as storage in drive G:. Is there something else that I need to change in BIOS or do I have to configure the jumpers differently? Please help! My current OS is XP and the motherboard is a Soyo Dragon Plus 2 (sy-p4i865pe). TIA
