MP 1,1-5,1 [HowTo] MP 3,1 Use AMD RX 580 for Mojave/Catalina and bootscreen (without flashing)

Well refind is loading and the logging is primitive but it shows that it is failing for graphics output. (!ok means “not ok”) so it could mean the card you have doesn’t have GOP firmware or perhaps a resolution is trying to be loaded that isn’t valid.
What settings do you have in your refind config file?
Correct. I read about this in the refind docs. He also suggested turning it off under certain circumstances.
Anyway, in my case, I am sorted and have no issues using the steps I posted.
Only thing of note is that I seem to be permanently in verbose mode and always get the text output after selecting a drive to boot and also at shutdown. I can live with this.
My card is an ASUS DUAL-RX580-O8G. I don't know if it has GOP firmware.
Not sure if my attached refind.conf (renamed to .log and zipped it up) made it. The only change I made was the timeout I believe...My monitor is 1920x180 and tried hdmi, displayport, dvi (gave purple screen).

Based on this thread it seems that ASUS may not be using a GOP firmware with the RX 580 that is fully functional (in other words they are using an old and buggy version).

depending how adventurous you are you could go this route to attempt to update the GOP portion of the rom in the GPU or try a different brand like a recommended sapphire pulse or even a physically massive powercolor red devil (both cards I’ve tested).

you could also try specifying a lower resolution in refind like 1024x768 or 800x600

Curious what make/model of RX 580 card do you have? Ludacrisvp may be correct in that my Asus card does not have the proper GOP firmware.

Thank you for this information. I'm going to read up about updating my card or I may source a sapphire pulse version of the RX 580. I'll report back.
It's from the link by Dayo under post #16. Essentially the same file in the first post.
I have the XFX one from OWC. They market it as an upgrade card for 4,1 & 5,1 MacPros. Not sure whether they have done anything to it before selling it. I bought it before gathering that the Sapphire Pulse version is the Apple approved one but it works fine as said.
Given that it works for you and only skips the rEFInd Boot Screen, why not just keep using it and if you need access to boot options, swap in your old card.
Yes I may just live with it but I'm anal & curiosity has now taken over. lol. Thanks for the info. & the help!
Only thing you may try is install the RX580 and you stock 2600XT at the same time and boot to an efi shell:
Code:
fs0:
drivers > drivers.txtJust copy the shell to your EFI partition and bless it like you do rEFInd.
@DearthnVader Can you explain a bit more what this shell does?
Also, what does the bit with "drivers > drivers.txt" fit in?
Also, what does the bit with "drivers > drivers.txt" fit in?
The fs0: command gives you the first mapped file system, normally the EFI partition you have booted the shell from.
The drivers command displays a list of drivers loaded on the system.
the > (pipe) command pipes the output of drivers to the file drivers.txt.
What we should see is the AMD GOP Driver, and what I am looking for is if the driver is loaded has passed the validation test.
The AMD GOP Driver has a validation test, is phrases parts of the PC Video Bios and runs a checksum on the "Protected" tables within the VGA Video Bios, such as the clock and voltage tables. If the test fails, the GOP driver won't work in a UEFI PC or a Mac in GOP mode.

When I compiled this version of rEFInd I don't have a Mac Pro. I had been using my RX580 for Ether mining, and had binned the card for max MH/s at the lowest wattage.
Later, when I got a MP3,1 on the cheap, I tried this version of rEFInd, but it didn't work for boot screens with my RX580 because I had edited the Bios protected tables for ether mining.
Flashing the OEM Bios back to the card fixed the issue.
If people buy their RX580 second hand, there is a good chance it was used for blockchain mining of some sort and has been binned.
There is also the off chance that even when buying new that the card vendor didn't validate changes properly before shipping the VBios.

This never really got pasted the testing stage, and several test versions got left in the upload to my google drive.
The hope was to get this working for the 3,1/4,1/5,1, and while several people with 5,1's did test, we were unable to figure why the 5,1 doesn't work for GOP boot screens with rEFInd.
The AMD GOP Driver does properly link and load on the 5,1, and if you use a Shell tool I compiled it will poll the GOP graphics card and return the EDID info from a connected monitor, but we still get no boot screens.
I don't own a 5,1 and I can't debug this remotely, one day, when the 5,1 can be had on the cheap, I may figure this out and release a new version, but the project is on hold for now, unless someone else takes it up.
Found out the culprit. Basically CC Cloner resets the boot volume as part of its housekeeping after running when the disk being cloned is the one it is running on (At least on APFS drives).
I presume it checks something and notices/thinks there is no startup disk and "fixes" this or perhaps it first unsets the disk it is running on before cloning and then "rectifies" this afterwards.
The daemon fixes such changes.

You know I compiled this version of rEFInd, and now I'm having the same issue you are, it no longer works on my 3,1.
I checked with my ScreenModes.efi and the system no longer outputs any GOP modes for a connected display.
I'm not sure what the issue is, but I did have to change my logic board after bricking one, I could have sworn I had they version of rEFInd working with my new logic board, but maybe I didn't.
Let's compare bootrom versions:
Code:
MP31.006C.B05Someone with this version of rEFInd working for GOP boot screens post their version of boot rom?
MP31.006C.B05 is the only firmware upgrade ever released for MP3,1, Mac Pro EFI Firmware Update 1.3, back in March 2008. Most of MP3,1s already had this version from factory since it was released less than two months after MP3,1 launch date.
Thanks @tsialex, this is odd, I can't figure what has changed, maybe something to do with bless on High Sierra.
I'll reinstall El Capitan and see if that is the issue, as I can't think of anything else that has changed.
