Msi 2.240
MSI has confirmed that version 2.240 will be the last update for select AM4 motherboards (B450/X470) before they enter "Legacy" status. If you own an older board, 2.240 may be the final feature update you ever receive. Archive the file on a cloud drive; in two years, MSI may remove it from their servers, forcing you to rely on sketchy third-party hosts.
Flashing a BIOS carries risk. Only perform this on a system with a working floppy drive or a bootable CD-ROM. Do not use Windows-based flashing tools. Msi 2.240
