I tried modifying the bios file to show the Advanced tab by patching PlatformSetupConfigurationDxe. I could already remove the whitelist and UEFIpatch can apparently remove the lock in the power management register automatically. Can anyone tell me how to patch the bios to show the Advanced tab? I analyzed the PlatformHiiAdvancedDxe part of the bios with Universal IFR Extractor and there are a lot of settings I cannot access right now. Bios is uploaded here: sendspace. com/file/vwhtgr Output from IFR is here: sendspace. com/file/ts3a35
