RAR archive of 2.26 MB containing firmware for the HP ProBook 4530s; the name states only the model, with no board number, platform or revision. Open it with an archiver such as WinRAR or 7-Zip and inspect the files inside to see whether it is a full SPI dump or a vendor update. Because the 4530s came with different boards, check the motherboard number and CPU platform before flashing. Read and back up the existing chip with a programmer, and ensure the image size matches the flash capacity.
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.
