BIOS dump for the ASUS K52JR laptop, board revision 2.3A, with the Intel Management Engine region cleared. That makes it suitable for writing to a replacement or corrupted SPI chip without carrying over the previous machine's ME state. The 1.73 MB RAR should be extracted before flashing with a programmer. Check that the motherboard revision printed near the board label reads 2.3A, and save the original chip first, since it holds serial and MAC data you may want to transfer.
