Hmm, I'm trying to unzip your highly compressed terms!So, I tried all your suggestions.
but I found sth.
sth = something?
Is this the first screenshot in your message above?So when option2 got me black screen with backlight on. It booted. I confirmed sound working and screen shot captured.
PF ID = platform ID.I changed PF ID to 0007 but the same. only I got boot(black screen with backlight on) with option2.
0007 = 0x3E9B0007.
In this case you just got black screen (no backlight)? Or the system got stuck at "IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0"?
I am still trying to determine which screenshots belong to which Option? Do all screenshots belong to Option 2 with Platform ID 0x3E9B0000?Plus, I tried with LVDS at index1 and the same black screen.
Option1 always make boot stucked in the same error.
Sorry for very iirregural result report. I tried so many different options.
The "About this Mac" screenshots show GPU name, but not the amount of VRAM. Are all of these screenshots taken with Option 2?
If so, please run IORegistryExplorer and select File --> Save As... and upload the IOReg file. That will provide important clues about Port numbers, av-signal-type, and connector-type.
