BIOS archive for the Lenovo ideapad 100S-14IBR, with the code 1501_01_01 in its name, which points to the motherboard reference used on this model. The RAR is 3.39 MB and likely contains an SPI flash image. Technicians use such files to revive a laptop that will not power on or show a picture because of corrupted firmware, writing it with a CH341A or similar programmer. Read and keep the original chip contents first, compare the board marking on the PCB, and check that the image matches the flash size.
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.
