The F2 BIOS was released less than two weeks after the F1 BIOS version. It's a billion to one change that you would get a board with an F1 BIOS, IF you lived in some third world country. Living in the US, there is ZERO chance. Any board you get right now will have been manufactured in the last 6-8 months, at MOST. The F2 BIOS was released March of 2019, so any board manufactured after that date would have AT LEAST that version, and most probably one that is much newer. Especially on a low cost board like this one that likely moves in much higher numbers than any of the top shelf flagship models do.
Plus, most of the 8th Gen chipset boards WILL support 9th Gen CPUs even without a new enough BIOS to fully support it. They just won't...
