Firmware package for an HP machine named T85 440 G8, on Quanta board X8Q with part number DAX8QAMB8D1 revision D, archived as a 20.7 MB RAR. The DA-prefix with MB is the Quanta motherboard pattern, and the trailing letter denotes revision. The contents are not listed, so extract them to see whether a full SPI dump or separate region files are included. Before programming with an SPI programmer, read and save the original chip and check the board revision matches D.
