As hamluis says, it really doesn't matter. You're not going to be able to have a SATA drive and an IDE drive designated Master and Slave on the same channel (Primary) as they're on two different controllers. The only thing Primary (1st Master/Slave), Secondary (2nd Master/Slave) and Tertiary (3rd...) means is a way of stating in English what port address the controller is allocated. When you swap drives around, controllers can get allocated different ports, but it shouldn't cause any problem.
If you really wanted it back how it was, you could see if the BIOS setup has a "Clear ESCD Data" or "Force ESCD update" option, or try clearing the CMOS memory, either may cause the port allocations to revert to how they were before. But I can't guarantee that.
