Working BIOS dump for a Lenovo board identified as IB365CX at revision 1.0, as given in the name, packed in a 6.69 MB RAR archive. Such an image is used to restore a motherboard whose firmware is corrupted, which shows as no display, power cycling or failure after an update. Write it with an SPI programmer such as a CH341A, keeping a backup read of the original chip so serial and system data can be restored. Check the board code and revision on the PCB and that the image size matches the flash chip before writing.
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.
