Confirm firmware before ordering
UnresolvedCore Ultra 5 250K Plus + MSI B860M GAMING PLUS WIFI
The minimum BIOS for this pair has not been confirmed. The board manual documents Clear CMOS and M-FLASH, but no CPU-less Flash BIOS Button procedure.
Build decision: Match 250K Plus in this exact board's CPU Support table, not the WIFI6E model. Before ordering, ask the seller to confirm the minimum supported BIOS, the version installed on the shipped board and that 250K Plus can reach POST. Arrange a seller update if needed.
Still to check: No minimum version or out-of-box boot claim is made here. The exact CPU support row and the delivered board's installed BIOS still need confirmation.
