I've started to build a home NAS solution based on AsRock J3710M and Syba SI-PEX40064 SATA controllers. As soon as I insert one or two SATA controllers in any of the PCIe slots, the bios POST fails and start a boot loop of 3 sec. at BIOS splash screen. These controllers work fine with an Asus P6T Deluxe v2 motherboard so it looks like a BIOS bug.

Here are the config details:

- MB: ASRock J3710M
- RAM: Corsair CML16GX3M2C1600C9 (2x8 GB kit)
- 2x Syba SI-PEX40064 PCIe x1 4 ports SATA controllers (Marvell 88SE9215)
- PSU: Seasonic M12II Bronze Evo 520W (SS-520GM²)

Thanks for your help,
