BIOS archive for an M495 laptop with LM495 board, Wistron number 11269-2, for the AMD CPU variant, in a 2.50 MB RAR. The dashed five-digit code follows Wistron's numbering, so Wistron is the ODM; the laptop brand is not named. The AMD note matters because Intel and AMD versions of a model use different boards and firmware. Flash it to the SPI chip with an external programmer only after checking the PCB number, backing up the original, and confirming the image matches the chip size.
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.
