BIOS .rom 8.00 MB Shared

Second copy of the Lenovo unlocked Yoga 11 BIOS in .rom format, 8 MB in size, with the sur token in the name unexplained. Holding two identical copies helps confirm the file was not damaged in transfer or reading. The image is intended for direct SPI programming and fits a 64 Mbit chip. Since the name does not detail what was unlocked or the board number, verify the target model carefully. Always store the board's original dump before writing a modified image.

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 @biosfilebins. Enginerys does not host this file.
