Another 2 MB BIOS dump labelled ASUS K42N, in .bin format with no revision, version or status given. The capacity matches a 16 Mbit SPI flash. A technician would use it to reprogram the chip on a K42N that will not POST, after checking the board marking. Because the source and condition are not stated, comparing the image with other K42N dumps or your own read is sensible. Back up the existing contents before writing and verify afterwards.
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 →
