hey,
I have a gigabyte H81M-S1 (rev. 2.0) motherboard. as I read on manual it shows
  1. 1 x PCI Express x16 slot, running at x16
  2. 2 x PCI Express x1 slots
    (The PCI Express slots conform to PCI Express 2.0 standard.)
now I have the rx470 graphic card installed. can I use PCIe m.2 adapters also and if I can then which one I should buy? and can I boot my pc from this m.2 SSD?
