Hey guys, I have an ASRock Z97 OC Formula mobo and I tried to update the BIOS and did everything that ASRock said to do and it failed. Now on my BIOS chip I have two options (A and B), the update failed on the A. So, does that mean that If i switch it to B that I can still run the PC or would the mobo be compromised?
