Hi. I've been using the DSDT override with testsigning set to on. However, I just bought and installed Ghost Recon Wildlands from Ubisoft and the game won't launch because it needs DSE to enable EasyAntiCheat. The solution they give on their site is:

bcdedit -set TESTSIGNING OFF

bcdedit -set NOINTEGRITYCHECKS OFF

Won't this disable my DSDT override and render my eGPU unusable? Is it possible to do this and then re-enable Testsigning or does the game and EasyAntiCheat need it permanently on?

Does anyone know how to get around this? 

Thanks!

   

An alternative non-registry method of loading the DSDT override is covered in the OP:

I have the same issue with another game using easy anti cheat.

Is the non-registry method safe now? Or is there still a chance to brick my MacBook (pro retina early 2013)?

@thatpickleman, kryptonite and automate-eGPU EFI bootloaders both have DSDT loading capability that may be more suitable for use with Macs than Clover outlined in the OP.

Hi,

I am following the guide with my Lenovo Thinkpad L570 (newest bios) and a am getting "asl_ERR: UnAsmOpcode: invalid opcode class 0" if I run "asl /u dsdt.dat" with my "dsdt.dat" (I am using the "Microsoft ACPI Source Language Assembler Version 5.0.0NT"). I dumped my DSDT with SSDTTime aswell and got the same DSDT with the same error. Using DSDT's from other people did not give me an error, so I assume I set it up correctly.

I searched in the thread but I did not find a solution to this problem.

Thanks for any help!

@nando4, Excellent! This worked for my iMac 12,2 early 2011, 27" boot camp with Windows 10 sound off issue, with test signing mode enabled.

@mwasking, good news. A couple of pointers to help you along:

1. audio-fix can be found at https://egpu.io/forums/postid/2614/

2. test signing mode can be eliminated by loading your DSDT via automate-eGPU EFI or Clover (as noted on opening post)

Once you have it all sorted consider sharing the goods news by completing a build guide to appear in the builds area

@lanzz, I think I have an eGPU setup very similar to yours (K95VB).

I had the same errors:

dsdt-modified.dsl 14323: ((QDEV (0x02) << 0x02) + Local0)
Error 6114 - Result is not used, operator has no effect ^

dsdt-modified.dsl 14324: ((QDEV (0x04) << 0x04) + Local0)
Error 6114 - Result is not used, operator has no effect ^

dsdt-modified.dsl 14325: ((QDEV (0x08) << 0x06) + Local0)
Error 6114 - Result is not used, operator has no effect ^

I just removed the corresponding lines, and it seems to have worked fine.

Hello,

I'm trying to pair Lenovo ThinkPad L570 with an eGPU, got code 12, so here I am, looking for hope.

The problem is, when I proceed to the each steps of configuration dsdt files, I'm stuck on command

asl /u dsdt.dat which receive as below:

asl_ERR: UnAsmOpcode: Invalid opcode class 0

 

The earlier steps was double - checked, dsdt.dat is present in dsdt directory with asl.exe . 

What Is wrong with dsdt.dat so it is not processing? 

Now I'm just waiting for hope (or Your knowledge).

Regards
