Once any new drive is installed you would first see if it is detected by the bios for making sure it's connected properly and a good working drive. The boot drive whether ide or sata will be seen at the top of the list when bringing up the drive list once highlighting the "hard drives" item seen in the boot order section.
If you are simply adding a second storage drive in you simply make sure the first OS host//boot drive remains on the top as the default drive. For seeing an upgrade from a smaller sata model with ide drives present and boot files and information on the first sata not an ide drive you would unplug any ide drveis first before installing any version of Windows like XP or Vista.
That will see the boot files as well as mbr entries placed on the new sata drive where later the ide drive(s) can be plugged back in. For the bios settings and general installation instructions refer to the board's user manual or support site for the download found there.
