BIOS archive for the HP ProBook 4520s, marked as the Intel Core i3 variant, with the codes H9265 and 448 4GK06, which look like HP and Quanta board identifiers. The 1.94 MB rar is used to reprogram the laptop's SPI flash with an external programmer when the board does not start or a BIOS update failed. Match the codes against the stickers and silkscreen on the motherboard before you rely on the file. Read and keep the original chip contents, which include the serial number and other machine data.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
