UnresolvedCore Ultra 7 270K Plus + MSI MAG Z890 TOMAHAWK WIFI
The original WIFI model has a Flash BIOS Button procedure that works without a CPU or memory. This update capability does not establish the minimum BIOS for 270K Plus.
Build decision: Match 270K Plus in the original WIFI board's CPU Support table and record its Result value. Ask the seller for the installed BIOS. If an update is needed, follow page 75 of this exact board's manual with its matching firmware; WIFI II firmware is for a different board.
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.
