How do I enter the BIOS setup on the MSI B550-A Pro?
Press the Delete key when the message 'Press DEL key to enter Setup Menu, F11 to enter Boot Menu' appears during the boot process. Once inside the BIOS, you can use function keys such as F6 to load optimized defaults, F7 to switch between Advanced and EZ mode, and F10 to save changes and reset. (Page 48)
