You're considering the MPG Z490 GAMING PLUS motherboard and wondering if your i7 10700F CPU is compatible with the default BIOS. The MSI site indicates the first BIOS version for this board was released in 2020, and it lists your CPU as supported. However, you're unsure if the default BIOS version matches what comes with the board. It's possible the motherboard includes an older BIOS. You might need to access the BIOS settings to check for updates or compatibility with your CPU model.
