BIOS image for Wistron board 19746-1, a 16 MB dump with no file extension, the size also stated in the name. A 16 MB image matches a 128 Mbit SPI flash chip such as a 25Q128 type part, so check the chip marking on the board before writing. Technicians use such a dump to reprogram a corrupted BIOS with a CH341A, RT809 or similar programmer. Read and save the existing chip before erasing it, since the original contains machine-specific data that a generic dump may not include.
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 @schematiclaptopramkushwaha. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
