Firmware archive for the UX301LA motherboard, marked as tested. The name gives only the model code, no revision or brand, so verify the board markings before relying on it. The 3.24 MB RAR contains the BIOS image meant for the SPI flash chip. Technicians program such files with a CH341A or similar tool to recover a dead or corrupted BIOS. Read and keep the original chip contents as a backup, since serial and network data live there, and ensure the image size equals the chip 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 @generalbios. Enginerys does not host this file.
