Firmware for the Acer Aspire A315-31, whose main board is the Quanta DA0Z8PMB8E0, revision E, in a 79.7 KB RAR. The DA0xxxxMBxx pattern is Quanta numbering. Such a small size suggests an EC image or a partial dump rather than a full BIOS, so inspect the contents carefully before use. Program it with an external SPI programmer after backing up the original chip. Confirm revision E on the PCB and check that the image size fits the target chip.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
