BIOS firmware for the ASUS N43J laptop mainboard, revision 2.3, packed in a RAR archive of around 1.9 MB. The name gives no version number or chip details, so inspect the extracted files and check the size against the flash chip fitted to your board. Technicians use a dump like this to rewrite the SPI BIOS chip with an external programmer when the laptop powers on without display. Read and store the original contents first and verify the board revision on the PCB matches 2.3.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
