Firmware dump for the HP EliteBook 820 G3, a 16 MB binary carrying the token 301 in its name, whose meaning is not explained and may refer to a version or a board marking. The size matches a 128 Mbit SPI flash chip. Technicians program such images with a CH341A or similar to recover a notebook that will not POST. Back up the original chip before writing, compare the board against the 820 G3, and expect to restore the serial number and product data after flashing.
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 @biosfilebins. Enginerys does not host this file.
