Apple BIOS CHIP Series

Source BIOS chips for MacBook logic board repair, covering MacBook Air and MacBook Pro models. On Apple logic boards the firmware flash chip stores the system firmware and board-specific data, and corruption here produces the familiar no-boot or black-screen failure that Apple diagnostics often misattribute to the whole board. Our replacement chips are programmed for the specific MacBook model ordered and verified before shipping, with clean firmware and no locks. This is a board-level repair part intended for technicians with microsoldering experience: the chip must be desoldered and replaced with correct orientation, and the firmware must match your exact board revision. If you are unsure which chip your logic board needs, send us a clear photo of the original chip marking and your MacBook model, and we will confirm the match before you order. Logic board repair demands precision, so each chip is programmed and verified against the firmware for your exact MacBook board revision before shipping. We support repair shops with consistent quality and quick turnaround, and every chip is covered against programming defects.
