Dear my friends
Please have a look at
It is said that PEPs can be used to provide or override any arbitrary ACPI runtime method.
And a sample project can be found at
I succeeded in overloading ACPI table with ACPIGenFx. But the overload can be active only when testsigning is on.
The used ssdt is attached.
I wish to do the same thing with PEPs in order to make my driver be able to run when testsigning is off.
But I even failed to test the sample project mentioned above.
After I installed the sample driver, it could be seen in device manager. However when the computer restarts, the computer failed and could startup by recovery.
Even when I modified the source code to a nearly blank device, the computer crashed in the same way.
(Deleted all source code except those for ROOT and SPBD).
The modified code are attached too.
Who can tell me what is the problem? or
Where I can find a tutorial (reference materials) about PEPs?
Thanks a lot.
