BIOS firmware for the Lenovo ThinkPad X1 Carbon with board number 12298-2, which follows the Wistron numbering pattern; the -2 suffix normally marks the revision. The ZIP probably holds an SPI flash image to rewrite with an external programmer. Use it when a board will not post or is stuck on a corrupted firmware. ThinkPad flash holds machine data and supervisor password storage, so save the original dump first. Confirm that the board number and chip size match before writing.
