|Sata hard drives don't have master/slave designations and to have two ide hard drives on a single cable means that one of them must be a master, either jumpered to master/slave or cable select.|
The master / slave issue on ide drives is only so they can share a single cable/channel. Sata hard drive only have one cable per device so no drive, or every drive depending on how you look at it, is master. The only issue becomes which is disk 0, disk 1, disk 2.... but this is normally not configurable short of swaping the ports the drive is connected to.
You can normally set the(or any in most cases) sata drive to be the boot device in bios, allowing it to boot to it without attempting to boot the ide disk.
