Acer firmware image for the 2920 model, 1 MB in size and without a file extension. The name gives no motherboard number, revision or BIOS version, so check the board before use. A 1 MB image suits an 8 Mbit SPI flash and is usually loaded into a programmer as raw binary to recover a corrupted BIOS. Make sure the chip capacity matches, read and keep the original contents, and confirm the PCB really belongs to an Acer 2920 before writing the file.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @abgm_manutencao_bios. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
