Preparing

SSDTs

In this repository we dump ssdt on our device which maybe doesn't work on your system

If you got kernel panic please using [SSDTTime] (https://github.com/corpnewt/SSDTTime) to dump your SSDTs

1. Start with option P. It dumps the current system's DSDT, which will be utilised in order to create these SSDTs and patches.
   • FixHPET (Choose option C which only patches conflicting IRQs from legacy devices)
   • USBX (choose the default option B key)
   • RTCAWAC
   • PluginType
     For AMD Laptop
   • FakeEC Laptop
   • PLNF
   • XOSI (Choose default A key)
2. Copy all the files that start with SSDT and end in *.aml inside of Drive /EFI/OC/ACPI
3. Finally, merge patches_OC.plist by using the PatchMerge script included with SSDTTime. Run it the same way as SSDTTime

Kext

• Replace WhateverGreen.kext with Nootedred.kext
• Highly recommend using itlwm.kext with HeliPort app
• MapUSB and replace UTBDefault.kext with UTBMap.kext

config.plist Setup

remove sample.plist

NVRAM

• boot-args: -v keepsyms=1 debug=0x100 npci=0x2000 vsmcgen=1
• add alcid=xx replace xx with your layout-id
• add agdpmod=pikera if you got black screen after boot

PlatformInfo

• Please change MLB/ROM/Serial Number/UUID by using GenSMBIOS
