BIOS dump for the Acer Chromebook 15 model CB3-532-C47C, supplied as a 1.88 MB RAR archive. The name states no board number or revision, so read the code printed on the motherboard before trusting the dump. Chromebook firmware is normally coreboot based and stored on an SPI chip, which a programmer with a SOIC clip can rewrite once write protection is handled. Read and keep the existing contents first, and make sure the extracted image matches the size of the installed flash chip.
