Lenovo BIOS dump for the ACLU1/ACLU2 platform on LCFC board NM-A272, revision 1.0, for the UMA version that uses integrated graphics only. The 8 MB file matches a 64 Mbit SPI flash. NM-xxxx is the board numbering used by LCFC, Lenovo's Compal-linked ODM, and ACLU1/ACLU2 is the project code silkscreened on the PCB. Do not use this image on a board with a discrete GPU, check the revision and back up the original chip before programming.
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 @abgm_manutencao_bios. Enginerys does not host this file.
