BIOS dump archive for an Ollee Snowbook, tagged snowbook0002, intended for a Winbond 25Q64FWSIG flash chip. That part is a 64 Mbit (8 MB) 1.8 V SPI device, so a 1.8 V adapter is required on most programmers to avoid damaging it. The 3.04 MB RAR holds the image for restoring a laptop that will not boot after a failed update or corruption. Read and save the existing chip content before erasing, and confirm the extracted file is exactly 8 MB so it fits the 25Q64 correctly.
