FIX for boot hangs after BIOS update (ACPI PATCH)

[mattystonnie]

I was going thru the bios setup and in peripherals there is ami output protocol policy and in it there is an Output Select, but the only choice is: DFPZ_HDMI. Don't know what this is and don't remember if it was ther before the bios update to 14.

I injected a framebuffer and updated WEG.
Try this one.
Are you using RX 580 right?
Can you install IOregistry Explorer and send me a copy of your ioreg?

No, I have a Sapphire PULSE Radeon RX 560 14CU 4GB GDDR5 PCI-E HDMI / DVI-D / DP OC Version (UEFI) - didn't have the $$ for 580.

Dont use that EFI folder, will not fix your GPU, it is for RX 580.

In your Bios enable multi monitor support, PEG/PCIE(RX 580) as primary, IGPU enabled DVMT pre allocated memory 128mb.

I'm sorry, but I cannot find any of these settings in my bios. Do you want me to install the efi above? Thanks again for all the help.

Yes try the EFI.

That efi hangs right after start ~1sec - stops at "End RandomSeed". And that is with monitor in hdmi. I didn't get a chance to try it in dp.

Fixed and I did a small SSDT for your RX 560.

OK, this works fine on hdmi but when I go to dp it hangs.
Last 2 lines are:
The parent of this AGDC <ptr> is = GFX8
Register AGDC <ptr> with AGPM class 8 GFX8

Leave it like that .
If you want to fix it search for AMD Framebuffer patch, its not easy.
