Raw 4.00 MB BIOS image named for the N61Ja, which corresponds to an ASUS N61Ja notebook model, although no brand field accompanies the file. A .bin of this kind is written straight to the SPI flash chip with an external programmer when the existing firmware is corrupted or the laptop fails to post. The 4 MB size should match a 32 Mbit flash chip; verify the capacity marked on your chip before writing. Save a full read of the original chip first, as it holds board-specific data such as serial numbers and MAC addresses.
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.
