Raw 4.00 MB BIOS binary for a unit labelled n53jn. The extra word ReferBish appears to be the uploader's own tag, possibly meaning a reference or refurbish dump, but its meaning is not certain. The file size corresponds to a 32 Mbit SPI flash chip, so it can be written directly with an external programmer once the board number is confirmed. Read and store the existing chip contents first, because serial numbers and MAC data live in the original image, and verify the write before reassembling the laptop.
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.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
