BIOS dump for the HP ProBook 450 G3 built on Quanta board DAX63CMB6C0, revision C, with the Intel Management Engine region cleaned so the image can be written to a replacement or corrupted chip without carrying over the old ME state. The zip holds about 8 MB of data, consistent with a 64 Mbit SPI flash. Read and save the original chip with a programmer such as a CH341A before writing, compare the board number and revision on the PCB, and keep in mind that serial number and product data may need re-entering afterwards.
