BIOS dump for an 840 G2, most likely the HP EliteBook 840 G2, labelled as having no password. The 6.02 MB RAR archive gives no board number or chip type. It helps when a supervisor password blocks access or the firmware is corrupted, and is written to the SPI chip using a hardware programmer and clip. Read and keep the original contents first so the serial and product data can be restored. Check that the image size matches the chip before programming.
