Firmware archive with a terse name pointing to a ThinkPad T14s, 26.4 MB RAR; no generation, board number or revision is stated, so the exact variant must be confirmed from the contents. Archives of this size often contain several dumps such as the main BIOS and EC images. Before writing anything with an SPI programmer, read and back up the original chip, identify the board number printed on the motherboard and confirm it matches the dump, and make sure the image size equals the flash 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 @free_bios_support. Enginerys does not host this file.
