BIOS dump for the ASUS ExpertBook P5440FF, sized for a 16MB SPI flash chip and packed in a RAR archive of about 5.15 MB. The OKOK tag in the name suggests the uploader checked the image and found it working. Write it with an external programmer such as a CH341A when the original firmware is corrupted and the laptop will not boot or shows no display. Read and save the existing chip contents first, since they hold the serial number and other unique data, and confirm the chip really is 16MB.
