Firmware image for the B_X133A board at revision 3.0, code E148299, associated in the name with the Multilaser PC231 and the ML-GW01 model tag. Packed as a 4.35 MB RAR, it is meant for writing directly to the BIOS SPI chip with a hardware programmer when a unit has a blank screen or boot loop from corrupted firmware. Compare the extracted file size with the flash chip capacity, back up the original contents first, and make sure the board label on the PCB matches before writing.
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.
