BIOS dump for a board labelled CE470 with the number MN-A821 at revision 1.0, in a 4.54 MB RAR. The name gives no brand, so identify the machine from the case and the PCB markings before using the file. Such an image is written to the SPI flash with a programmer when the system will not POST, shows a black screen or failed during an update. Check the MN-A821 marking and revision on your board, read and save the existing chip first, and confirm that the image size matches the flash capacity.
