BIOS for the Lenovo ThinkPad Yoga 260, intended for a Winbond W25Q128 SPI flash, a 128 Mbit chip equal to 16 MB. The archive is an 8.10 MB RAR. Clip the chip with a programmer such as a CH341A or RT809H, read and save its contents, then write this image to repair a corrupted BIOS or a no-boot board. Make sure the fitted chip really is a W25Q128 or another 16 MB part, since an image of a different size will not fit.
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.
