Lenovo BIOS archive for the board identified as IQ67I, revision 1.1, packed as a 5.12 MB RAR. The name gives no laptop model or ODM board number, so identification relies on the IQ67I code and the revision printed on the mainboard. Such dumps are typically written to the SPI flash chip with an external programmer to fix no-boot or corrupted firmware conditions. Back up the existing chip contents before erasing, and check that the image size matches the flash capacity, since a mismatched file 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.
