Xiaomi RedmiBook BIOS Dumps

4 files across 2 boards and models. Most common chip sizes: 16 MB (1). 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.
