Zyxel BIOS Dumps

16 files across 4 boards and models. Most common chip sizes: 4 MB (3) and 8 MB (2). A BIOS dump is a full image of the board's SPI flash chip. It is written back with an SPI programmer when the original firmware is corrupted, after a chip replacement, or to recover from a failed update. Read and save the original chip first: serial number, DMI data and the Intel ME / AMD PSP state differ between boards.
