hi , i have the Z97-PRO(Wi-Fi ac)/USB 3.1 motherboard and a 4th gen cpu ( Intel Core i7 4790K @ 4.00GHz )

when i start my pc i see A2 on the motherboard and the AMERICAN MEGATRENDS screen shows and says that i have to update my BIOS.

the problem is, i don't know anything about the right BIOS version and how to update it. i have the ( American Megatrends inc.2303, 3/2/2015 ) version

how can i update it or what should i do?
