You just need to install a boot loader in the SATA drive on port 0. There are some different choices. You can look around and pick one. I've tried two so far. BootMagic, which I used for a while. It came with PartionMagic. But once I installed SuSE 9.1 on the same hard drive as Windows 2000, I put a linux boot loader called Grub, which I now use to pick either Windows or Linux. I bet there are a few other loaders out there. When you first boot up, the bios checks the order of the hard drive boot. If you have it set to port 0, it goes there and quickly finds the boot loader. Then it checks your configuration, and you have 5-10 seconds to pick the boot up. Pretty straight forward.
