A (hopefully) final update...

Since the board didn't work properly with either the F2h BIOS or my Cooler Master power supply, I obviously had two issues which needed fixed. Since flashing the new BIOS and borrowing a power supply from a friend, every issue is gone... and there were a lot of issues to contend with. BIOS settings no longer change on their own so there are no more issues with Hot Plug Capability, XMP Profiles or Marvell RAID changing back to default settings. I can now enter the BIOS using my USB keyboard, the sound level wheel on my keyboard now works, the sound on/off button on my keyboard now works, my HP LaserJet 1320 printer now works on a USB3 Port... and I forget what else. I received my new Corsair power supply yesterday and installed it so I can return the one I borrowed but I expect everything to continue working normally.

A final thank you for helping.
