BIOS package for the ASUS K52JR laptop, board revision 2.3A, compressed with 7-Zip and marked tested OK. Revision 2.3A is stated in the name, and other K52JR dumps in the index cover revision 2.2, so confirming the version printed on the motherboard matters before flashing. Technicians use such images to recover a dead or looping board by writing the SPI flash with an external programmer. Read and keep the existing chip contents first, and check that the image size matches the chip.
