Custom HP Z840 BIOS Support

[Sophistophat]

Please implement custom HP Z840 BIOS support in this tool. I can't offer much to help, but I'm happy to tip payment addresses.

I own two of these machines and they're great; I want to help the community get everything that can be got out of them; still tons of untapped potential, rough edges that need smoothing, secrets to be teased out with them. There's already great work happening with its close cousins, Z420, Z620,Z820. See: HP_Z420_Z620_Z820_BOOTBLOCK2013_BIOS_mod

Getting support added to your tool here will be an important step in the process. Thank you for your time and expertise!
