ASUS K42N firmware with no file extension, 2 MB in size, which suits a 16 Mbit SPI flash chip. No revision or status appears in the name. The file is likely a raw chip image and may need a .bin extension before some programmer software will open it. Check the board marking and, ideally, the content against a known dump before use. Always read and keep the original chip contents first, and verify after programming.
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 @bios_laptop. 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 →
