I rarely help with such but if you give a link to your board I'll look. These sort of updates are treacherous so I rarely write how to do them. I must defer to the maker. I will quote the maker's instructions but in this case, please supply a link so I can check it out and see if there is more.
So, I'm needing to update my bios for my new cpu (AMD FX 8350 4.0 Ghz) to be able to run fully. The problem is, When i go to the website to download an update, I just get a .cap file. I've tried updating it with that file but EZ Flash says no. So i was on the look out for a .cap to .rom converter, turns out that is what i needed and they gave a list to all of their converters but none was for my model of MOBO (which is a M5A99X EVO R2.0) Please help with this, I've been at it for at least 4 hours and i have had no luck with any other forums. Thank you in advance.
