ASUS P8Z77-V LX motherboard BIOS, version 2501, supplied as a 4.25 MB ZIP. This is an Intel Z77 chipset desktop board, and the archive likely contains the firmware image for recovery or programmer flashing. Official ASUS capsule files often carry a header that must be removed before writing raw to the SPI chip, so check the file size against the flash chip capacity. Always read the original chip and keep a copy before programming, and ensure the board model printed on the PCB is the LX variant rather than another P8Z77-V edition.
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.
