Description
BIOS dump for a Lenovo X1 laptop, supplied for a 2 MB SPI flash chip and packed as a ZIP of about 5.6 MB. The original file name, LENOVO_X1_carbon14282_2m_CPU_I5_6th_generation_SR2EY_U49_MX25L12805.zip, points to a 6th generation Intel i5 build and an MX25L12805 flash part, though you should confirm these against your own board before flashing. Technicians use a dump like this to reprogram the SPI chip with a programmer after BIOS corruption or a failed update.
For the Lenovo X1 the catalog also has 2 schematics, 1 boardview file, and 7 BIOS dumps.

Questions about this file
How do I flash this BIOS dump?
Write it to the SPI flash chip with a programmer such as the CH341A and a SOIC8 clip. Read and keep the original contents first, and check that the chip size matches the dump.
Will this BIOS work on my board?
Only if the board number and revision match: Lenovo X1. Dumps from a different board or revision can leave the board dead.
What does “clean ME” mean?
The Intel ME region in the dump has been reset, so it can be used on another board of the same model. Keep your original dump and transfer serial numbers if needed.
