ASUS N46JV BIOS at version 209, stored in a RAR archive of 3.15 MB. The file may be either an official update capsule or a raw chip dump, so inspect its size and header before deciding how to apply it: capsules go through the ASUS flash utility, while a raw image is written to the SPI chip with a programmer. When programming directly, back up the original contents first to preserve serial numbers and the MAC address, and make sure the board really is an N46JV.
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.
