Not each port, its usually a setting which seperates ports 1-4 and ports 5-6. For example:
Serial ATA ports [0,1,2,3] mode: [disabled/ide/ahci/raid]
Serial ATA ports [4,5] mode: [As SATA type / AHCI]
Post a screenshot of your BIOS, with serial ata transfer mode included. Its different from the boot order, it should be somewhere in advanced features, onboard devices or chipset features, etc.
