Working BIOS dump for Lenovo board IQ1X0MS revision 1.0, named here as ThinkPad, covering flash chips U4 and U27 according to the file name; the RAR is about 13.8 MB. Since two chip locations are given, the archive likely holds separate images, each to be written to its matching chip with an SPI programmer. Confirm board number and revision on the PCB, check each image against the size of the chip it goes to, and read out and store the original contents of both chips before flashing anything.
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.
