BIOS archive for the LOS-1 motherboard, board number 12289-2, with an 8 MB image stated in the name. The 12289-2 code fits the Wistron board-numbering scheme, where the suffix marks the board variant. An 8 MB file suits a 64 Mbit SPI flash chip, so it is meant for direct programming when a board is dead or stuck on a corrupt BIOS. Unpack the RAR, compare the PCB number, back up the current chip contents and only then write and verify the image.
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.
