BIOS archive for a P553UJ notebook mainboard, revision 2.0, in a version fitted with an Intel Core i5 CPU according to the name. The 5.94 MB RAR likely holds an SPI flash image to be written with an external programmer such as a CH341A. Confirm that the board revision on the PCB reads 2.0 and that the CPU matches. Read and save the original chip contents first, and check that the image size equals the flash capacity, otherwise it will not fit.
