BIOS archive for an EXO Smart R3 notebook, identified by the board or model code MBPNCBT414-1320 in the name. EXO is an Argentine brand, and the code appears to be the mainboard reference rather than a standard ODM board number. The RAR is around 3.2 MB. Use the image to rewrite a corrupted SPI flash with a programmer such as a CH341A. Before writing, match the code printed on the PCB, save the current chip contents, and confirm the file size suits the chip capacity.</br>
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.
