Second copy of a ThinkPad X1 Carbon 7th Gen firmware package for machine type 20QD, a Lenovo RAR archive of 8.18 MB, the same size as the unnumbered version. No board number, revision or BIOS version is stated, so compare its contents against the other copy before flashing. Such dumps serve to recover boards with corrupted BIOS via an external SPI programmer. Always back up the existing chip, verify the read twice, and check that the dump size equals the chip capacity.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosfilebins. Enginerys does not host this file.
