Second variant of the Lenovo ThinkPad X1 Carbon 8th Gen type 20U9 firmware package, a RAR of 8.93 MB, slightly larger than the other copy, so the contents may differ. The name gives no board number or BIOS version. Compare both archives before choosing one to flash. These images are written to the SPI BIOS chip with a programmer to revive boards that will not POST. Always read and keep the original chip contents and make sure the image size fits the flash.
