Greetings forum members ,
I had no hand in creating the patched atikmdag.sys , it is all Lordkag of Fernando's Win-Raid forum work .
My only contribution is contacting Lordkag for another issue I needed help solving with Fiji custom ROM and asking if he knew of a fix to allow custom ROM usage on Polaris.
IIRC and what I understand, he has highlighted the permanent solution would entail driver/patch being signed and no need to disable driver signing in OS to use the patch. I have no ETA on when this would occur.
I would kindly & respectfully ask members using the Lordkag patched atikmdag.sys to make a donation on Fernando's Win RAID forum as way of thanks & appreciation for the help.
Here is link to Polaris bios editor, there are threads on OCN, Reddit, etc by author/users with interest in bios mod. Now we can use it thanks to Lordkag patch on driver and AFAIK the patch is for atikmdag.sys for Windows 10 driver.
All the best
Gup
