Hi there, I have a b550m itx/ac and I wanted to get some more SATA ports on it for more storage since its going into my NAS system. I got a StarTech 2-Port PCI Express to SATA Expansion Card which said plug and play yet when I plug it in, it doesn't seem to work. Confused, I tested with another PC I have and it does work. I'm running a 4600G as my CPU. Is there a BIOS setting or something that I need to enable to get it to function? I've seen forums saying this but there were for different vendor boards. |

windows doesnt see it? if you want bios to see it, then the only purpose for it would be to utilise built in raid or to boot from drive connected to that sata adapter bios shouldnt see that card as it has its own bios ooprom which works only when CSM is turned on (legacy bios) and storage set to legacy and loading optional ooproms is enabled in bios setup ------------- http://valid.x86.fr/diq4l4" rel="nofollow">  http://www.userbenchmark.com/UserRun/47132492" rel="nofollow - userbenchmark |

| I also built a NAS system using the b550m itx/ac motherboard, mainly because it was one of the few options for ITX available. NAS is a 5 bay but the motherboard only has 4 SATA ports so I added a PCIe expansion card with two extra SATA ports. Previous tried replacing the WIFI card with and M.2 A+E two port SATA card. When that didn't work I bought another thinking the first may be bad. When the second didn't work I bought a PCIe card with two SATA ports. Problem is the 5th drive isn't being recognized in BIOS. When I boot to Unraid the same, I see four of the five drives. Is it the motherboard that is the issue? I have replaced cards, cables and drives. I know all the parts are good. |

external sata card does not interact with mainboard sata controller, thats why you cant see it in bios and bios wont detect your drives connected to such external sata card, because bios doe not have drivers (modules) for it if sata card has ooprom (bios driver), then you can enable ooprom loading (in bios setup) so that bios driver gets loaded after mainboard finishes POSTing (befor OS loads), connected drives would be than shown there if there is no ooprom or its not compatible with your bios/uefi mode, then OS wont see your drives until you install driver for that sata controller ------------- http://valid.x86.fr/diq4l4" rel="nofollow"> http://www.userbenchmark.com/UserRun/47132492" rel="nofollow - userbenchmark |
