Working BIOS for Wistron board 18836-1, platform A1_WL, marked as fully working by the uploader. The archive is about 7 MB and gives no firmware version. Other dumps for the same board, including one used in Xiaomi notebooks, exist, so compare their sizes and contents. Write the image to the SPI flash with an external programmer when the machine fails to POST or shows a black screen. Keep a copy of the original chip and confirm the image size matches the flash chip.
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.
