I have a motherboard (OY2MRG), i5-2300, and 8GB of RAM from an old Dell XPS-8300 that I am using for my unRAID server. Recently I have started getting back into storing media on this server and so I picked up a couple of 12TB HDD to add to the server for more storage. I also bought a PCIe to SATA adapter to add more ports as the 4 onboard were already in use. I bought this one as it has the ASM1064 chip which I read is supposed to be supported by unRAID. I got everything installed and powered on the system, but the BIOS nor unRAID see the drives. The card has some LEDs on it and they turn on when the PC boots up, but go off as soon as post completes and do not come back on. The BIOS is severely limited in its options (it's a Dell after all) and I don't see any options that jump out at me but I'm certainly open to suggestions. Otherwise it looks like I'm limited to 4 SATA devices for the time being until I upgrade the platform (which might be sooner rather than later if I can't get these drives working, lol). I tried 2 of the 3 PCIex1 slots and neither worked (but showed lights during boot). The third slot has a NIC in it as the onboard NIC died years ago. The x16 slot is unavailable but I may be adding a GPU to this server as well for transcoding.

 

I added the diagnostics just in case (think I did it correctly).

The controller is not being detected by Linux, this is not a software issue, try a different PCIe slot, or try the controller in a different PC, to confirm it's working.

Thanks. I tried all other slots and it looks like it works in the x16 slot only. Bummer, at least for adding a GPU later, but the drives are showiung up in unassigned devices now at least.
