  It is very common hardware: ICH10 on MS-7522 (MSI X58 Platinum) motherboard:

ahci0: <Intel ICH10 AHCI SATA controller> port 0xb000-0xb007,0xac00-0xac03,0xa880-0xa887,0xa800-0xa803,0xa480-0xa49f mem 0xf9ffa000-0xf9ffa7ff irq 19 at device 31.2 on pci0
ahci0: [ITHREAD]
ahci0: AHCI v1.20 with 6 3Gbps ports, Port Multiplier not supported

  And Samsung F3 drive:

ada1 at ahcich1 bus 0 scbus1 target 0 lun 0
ada1: <SAMSUNG HD754JJ 1AJ10001> ATA-8 SATA 2.x device
ada1: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 8192bytes)
ada1: Command Queueing enabled
ada1: 715404MB (1465149168 512 byte sectors: 16H 63S/T 16383C)

  I'm not sure, that it is possible to update firmware on these
drives. And MoBo BIOS looks like latest one.
