Second 1.39 MB RAR archive of HP 630 BIOS firmware, likely an alternative copy or variant of a similar package. The name states no motherboard number, chipset or version, so open the archive and check its file sizes against the flash chips on the board before use. Such dumps are used to recover laptops stuck with no POST or a failed update by programming the SPI chip directly. Keep a backup of the original chip, and compare checksums against the other HP 630 set to see if they actually differ.
