My itx motherboard cannot boot and has flashback button, no. I take 8gb, 16gb USB stick. I've tried "cleaning" on disk part and "formatting" use bootice. But nothing works. I tried the names of MSI.ROM, but nothing happens. I did this once a year and half ago, but cannot find how to do it.. again. What is the name of the bios that only B450 gaming plus ac boards recognize? I remember it was something strange like c798345hd.ck7. (no, this is not it! This just hypothetical example!). It's a special name that only MSI b450 boards recognize. But what I remember was this motherboard turned on by itself after plugging it in. I remember my whole PC was built when it began flashing when usb plugged in. Red lights came out of my motherboard which I didn't even know was there. Why no instructions now?
Also, the manual doesn't say: what is my usb flashback port, again? It was it top two or bottom two usb? The manual changed so many times on website.
