BIOS image for a board labelled A14HV0X, revision 4.0, in a 2.65 MB RAR. The name does not state the manufacturer or the device, so identify the board by the marking on the PCB before using it. A companion UEFI version with the same revision also exists, so check which firmware type the board originally ran. The dump is written to the flash chip with a programmer. Back up the original chip first and verify that the image size matches the installed flash capacity.
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.
