BIOS image for an HP device labelled G640 G1, marked UNLOCK, which usually means the BIOS password or locks have been removed or the image modified to bypass them. The 16.0 MB .bin file matches a 128 Mbit SPI flash chip. Technicians write such files with an external programmer to clear a forgotten supervisor password or recover a locked machine. Back up the original chip before flashing, since it holds the serial number and unit-specific data that may need to be restored.
