BIOS dump for a DNS laptop on Pegatron board B74Y rev 2, read from a Winbond W25Q64FV, an 8 MB (64 Mbit) SPI flash chip. The ZIP is 3.32 MB, the compressed form of the 8 MB BIN. Pegatron is the ODM here, DNS being the brand that sold the machine. Match the B74Y code and revision on the PCB, save the original chip contents before programming, and confirm the extracted image is exactly 8 MB to suit the W25Q64FV.
