The newest 3.06 BIOS addresses Spectre and Meltdown vunerabilities. If you are going to update/flash the BIOS that would be recommended. You will probably have to flash to 2.99 first before you can go to 3.06. That's what HP states. When flashing BIOS connect to a backup power supply first if your electrical grid you connect to is unreliable. If the power would go out during the flashing process at worst you'd need to buy a new motherboard for the equivalent of 20 USD from Ebay.
If you have no idea what DSDT is do some research/study before trying to patch it. You really need to know what you're doing there. Definitely correct the DSDT after you have flashed up to 3.06 successfully.
If you or anyone else wants the 3.06.BIN file I've attached it to this post in the High Sierra guide. When flashing from within Windows of course, you need the .exe file instead.
I have updated BIOS to 3.06 uneventfully. As you have stated you need to update to 2.99 first and than 3.06. HP's Windows update utility has stuck multiple times and used BIOS's Flash ROM utility. I have prayed not to have a power cut. It has not happened luckily
I will study about DSDT. See how it goes.
