Firmware archive for the HP ProBook 450 G4, Quanta board DA0X83MB6H0 revision H, packed as RAR at 5.05 MB. Quanta encodes its boards as DA0, project code X83, then MB and revision letters, all visible on the PCB silkscreen. The archive most likely holds the BIOS image for the SPI flash, written with a programmer for recovery of a dead or bricked board. HP ties some data such as serial and product IDs to the chip, so keep the original dump, verify revision H, and check the image fits the chip.
