Firmware archive for the Acer Aspire A515-55 using the Quanta DAZAUIMB8C0 board, revision C according to the name. The 4.91 MB RAR most likely contains a BIOS dump intended for direct programming of the SPI flash with a hardware programmer such as a CH341A or RT809. DA-prefixed numbers with an MB suffix are Quanta motherboard codes. Make sure the revision on the PCB matches, dump and keep the original chip contents as a backup, and verify the image size equals the chip capacity before flashing, otherwise the write will fail or brick the board.
