I do expect some hassles with actual board to get fully configured.
This is one of the Gigabyte boards that features dual-Bios on the
board directly.

There is no flash chip socket on this board, and I do not have another
computer that features a serial port.

Actually, on a side note, what's the past trial and error that
happened when dealing with other gigabyte boards that feature a
dual-bios setup? On this board, there is two flash chips:

I don't know what the ITE IT8720F super i/o chip clearly states that i
cannot write to the bios on this chip, and when you look at the board,
The chip is physically located over near the PCI Slots near the edge
of the board.

The other flash chip is the south bridge for the board. This is
located over near the SATA ports under the heatsink.

And finally, I do know that the bios chips are located near the
southbridge. They have labels of M_BIOS, and B_BIOS.

I know that there is a similar board already supported in CoreBoot...
That board is the Gigabyte MA785GMT-UD2H.

The only differences on this is that the dual-bios is located near the
Super I/O  that  near the main power connector.
