BIOS image for the ASUS Prime B350-Plus desktop motherboard, revision 1.05, packed in a RAR archive of about 5.22 MB and labelled as a working dump. A technician would use it to recover a board that fails to POST after a corrupted update by writing the image straight to the SPI flash with a hardware programmer such as a CH341A. Confirm the PCB revision printed near the slots matches 1.05, read and save the original chip contents first, and check that the extracted image size equals the capacity of the flash chip 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 @biosarchive. Enginerys does not host this file.
