BIOS firmware for the ASUS K501LX laptop, revision 2.0 board, delivered as a 3.52 MB RAR archive. A dump like this is used to revive a unit with a corrupted or failed firmware chip by writing it to the SPI flash with an external programmer. Always read the existing chip first and keep that copy, since it may hold the serial number and system data. The image size must match the capacity of the flash on the board, and the 2.0 board revision should match the one being repaired.
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.
