BIOS image for the Chuwi GemiBook Plus, model CWI620, intended for a 16 MB flash chip and packed into a 6.26 MB RAR. No board number appears in the name, so compare the motherboard print and the chip marking before use. Such a dump is written with an external SPI programmer to revive a laptop that will not boot after corruption. The extracted image should be exactly 16 MB to match the chip. Read and save the original contents first, since serial numbers and other unique data may be stored there.
