BIOS archive for the HP ProBook 450 G6 notebook on board DA0X8JMB8E0, revision E, in a 6.73 MB RAR file. The DA0 prefix follows Quanta numbering, meaning Quanta built the mainboard for HP. Such a dump is written to the SPI flash with a programmer such as a CH341A when the laptop fails to boot or the firmware is corrupted. Read and save the original chip first, since it holds serial and board identifiers, and ensure the extracted image size matches the flash capacity before programming.
