BIOS image archive for the Lenovo ThinkBook 13s Gen 2 ITL, with board code LV550 13 MB and number 19869-1. The five-digit dash number matches the Wistron board numbering scheme, so Wistron manufactured the board, and ITL denotes Intel Tiger Lake. At 14.4 MB compressed, the pack likely contains a full SPI flash image for recovering a board with corrupted firmware. Flash with an external programmer only after confirming the board number, saving the original chip contents and checking that the image size fits the chip.
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 @biosarchive. Enginerys does not host this file.
