I have a [https://support.hp.com/ie-en/document/c04843458](https:// HP ProDesk 400G2 mini pc ), I want to enable the intel DCI function, but this bios does not have a corresponding menu, or even a hidden menu (using UEFITool.exe and ifrextractor.exe), so I first use ch341a to back up the bios, and then inject relevant instructions into the SiInit and SiInitPreMem modules. But after the modification, the machine cannot be started and an alarm will appear. What I want to ask is
Is there any relevant protection in bios and how can I bypass it? Thanks
