1 MB BIOS binary for an ASUS laptop listed as F835S, with the name referencing a 25L8005 flash, an 8 Mbit SPI chip family made by Macronix as MX25L8005. The size matches that chip capacity exactly. It is intended for reprogramming the BIOS chip with an external programmer when the notebook powers on without display. Model F835S is not a common ASUS code and may be a typo for F83S, so confirm the board marking carefully, and back up the chip before writing.
