BIOS image for the ASUS K53SV notebook, the name giving only the model with no revision or board details. The 4 MB size corresponds to a 32 Mbit SPI flash chip as fitted on this generation. Technicians write it with a hardware programmer such as CH341A or EZP to restore a board that powers on with no display. The K53SV uses NVIDIA discrete graphics, so do not apply it to other K53 versions without checking, and save the current chip contents before reprogramming.
