I was trying to do the bios update for the MSI B550-A PRO motherboard to enable use with an AMD Ryzen CPU. I was attempting to do the "Updating BIOS with Flash BIOS Button" directions on page 46 of the manual.
I downloaded the latest BIOS file for my motherboard. I renamed the file MSI.ROM, and saved it on the root of the USB drive. I connected the PSU to CPU_PWR1 and ATX_PWR1. I connected the USB drive to the BIOS flash port.
Powered on the PSU, then pushed the flash button. The red light flashed a few times, then went solid red. But the manual says the light will flash a while, then turn off when the BIOS update process is complete.
It's been a while, and the light is still on solid red with no flashing. What should I do now?
I searched the web for this error, and one person claimed a solid red light (for an earlier MSI motherboard) indicated that the motherboard doesn't recognize the flash drive. And some other people are saying you need to format the flash drive to FAT32 format, which I didn't do because the manual directions I referred to earlier in this comment did not direct me to format to FAT32.
So the red light is on right now. I read somewhere that interrupting the power during the BIOS flash process can be really bad to do, so I don't know how to proceed. Should I power the system off, remove the USB, check the USB format and see if I can get it to FAT32 and then replace the BIOS file on it and try the flash process again? Or would turning off power and doing this cause some sort of problem?
And why would FAT32 format be necessary if the manual doesn't direct me to do it? How to proceed?
