BIOS for the ASUS N56VM and N56VZ laptop, mainboard revision 2.3, with the flash chip named as a 25Q64FV, delivered as a 3.65 MB RAR. The 25Q64FV is a 64 Mbit, 8 MB SPI part, so the extracted image should be exactly that size. Program it with a CH341A or similar tool when the board shows no POST. Read and preserve the original chip before erasing, and confirm that revision 2.3 is printed on your mainboard, since other revisions may need different firmware.
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.
