BIOS dump for the Acer Z1402 with motherboard marking MBPNDBU144-0320, labelled OK, meaning it was reported as working. The MB string looks like an Acer service part number rather than an ODM board code, so confirm it against the sticker or silkscreen on your board. The RAR archive holds the image for writing the SPI flash with an external programmer when the laptop fails to boot due to corrupted firmware. Save the original chip contents before writing and verify the file size matches the chip.
