RAR archive described as a backup for an X705 machine, filed as BIOS or firmware, 5.42 MB packed. The name gives no board number, revision or chip details, so the exact contents have to be confirmed after extraction. A backup like this is normally a full read of the SPI flash chip, used to restore a board after a corrupted update or a failed repair. Before writing it with a programmer such as a CH341A, read and save the current chip contents and compare the image size with the flash capacity on the board.
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 @zinfoservicebios. Enginerys does not host this file.
