EXP GDC eGPU로 그래픽카드를 인식못할때 DSDT override 설정하기
(장치관리자에서 pci브릿지 등 살펴보면 인식못한것에 대한 설명이 있다)
오류코드 12확인(장치 사용 가능한 리소스 부족)
DSDT(Differentiated system Description Table)-ACPI(Advenced Configuration and Power Interface) 구성의 일부분
> DSDT 패치 - 시스템 사용 제한이 걸려 있는 부분을 커스텀 패치하여 사용 가능하도록 한다.
과정중에 %iasl%\iasl DSDT_MacbookP_EGPU.dsl 에서
Length가 다르거나 오버값이라고 에러가나면
헥사코드로 max-min+1을 해서 length에 넣어주고 진행하면 된다.
