RAR archive of HP BIOS firmware labelled 08BAD, which is the HP board or system ID code the image is meant for; no model name is stated. HP uses these four-character hexadecimal IDs to identify system boards, so match it against the sticker or the ID reported by the current firmware. Extract the contents and check the image size against the SPI flash chip before programming. Dump and keep the original chip first, since HP images also carry serial and DMI data unique to each unit.
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 @vinafix_bios. Enginerys does not host this file.
