GOP Boot Screens part II(Clover)

[DearthnVader]

In my never ending quest to get GOP boot screens working on the 4,1/5,1, I've had an odd day.

I won't go into all of it, however I have something new for 4,1/5,1 users to try. Clover in UEFI mode, installed to an HFS+ partition of a Master Boot Record disk.

First thing you need to do is make an MBR disk and add one HFS+ partition, can be USB or a SATA disk.

Next copy this folder to the root of the disk:

https://drive.google.com/open?id=1O-NadML8iKycC4UQsDZguXUS01fv-jiV

Install a GOP card with a Mac EFI card and reboot, holding Option.

You should see a disk that is EFI Boot, boot from that disk and see if Clover doesn't load on you GOP video card.

Let us know how it goes.

Created a HFS+ drive in MBR mode
Copied the EFI folder to the root of the drive
Replaced the config file with mine. (PBR boot option)
Blessed the Efi file and rebooted to black screen.
After pressing enter booted to my 1st drive (it happens to be Win 10)
Rebooted to Mojave and tried to find the debug file in the MISC folder. There were no files created.
Do I need to plug in my GT-120 in the second slot to see something? What am I looking for?

You don't want to bless the file, install both Mac EFI card and a GOP card, hold option at boot and look for the boot entry EFI Boot on your Mac EFI screen. Boot from it, with any luck you'll see Clover on the screen of your GOP card.

Just a reminder, if your signature is correct. You may not able to follow the instruction.

TempoSSD card has very high chance to hang the Mac EFI boot manager (hold option boot).

If you want to test this Clover boot, please make sure no bootable volume is installed on the TempoSSD card.

Strange I have never had a hang problem with neither Clover nor Refind or Next Loader, but I will test it both ways to compare

Direct load to any boot loader is fine. The problem is you can't "hold option" to boot with TempoSSD card.

Sonnet know about this loooong time ago. They told me that they will fix it about 5 years ago, but never release any update.

 

[LightBulbFun]

I gave this a quick test

with my Radeon HD 7950 Mac EFI connected to a DP Monitor and a UEFI GeForce GT 740 with a DVI screen plugged in

sadly clover only displayed on the 7950 and the GT 740 screen remained blank, also checking graphics properties in clover only showed the 1 Radeon HD 7950 and no mention of the GT 740, I do wonder if it goes back to what I tested in that the GT 740s UEFI OptionROM is not loaded by the Mac Pros EFI at all

I can confirm that I have never had such a problem as described by TempoSSD.

Yes, it won't work if the GOP rom is not loaded by the Mac Firmware. @h9826790 found that the RX580 GOP firmware got linked and loaded in his 5,1( In the older thread ).

Not sure if nVidia uses a rom check the way AMD does, if you edit the protected tables in the Vbios section, the GOP rom will load as INVALID, and thus can't be used in a UEFI PC/Mac.

I'd be interested in the output of the drivers command with both your GFX cards installed, if you can get to the Clover Shell. I think it will work, the correct shell for my 3,1 is the Shell64.efi, and I think I renamed it in the linked download to Shell64U.efi, because that is the one Clover loads from the graphical menu.

I just built the latest version of Clover( HEAD ) with the code that works for the 3,1 in rEFInd. I don't think it will work for the 5,1, but I'll upload it if anyone wants to give it a shot?

the GT 740 is completly stock

you can see a drivers output with my Radeon HD 7950 here, this was from the 140 BootROM thread

as for the GT 740, it does show up in the drivers list at all but it is detected as a PCI card when i list the PCI devices in an EFI shell which you can read about here https://forums.macrumors.com/thread...tscreen-support.2148023/page-10#post-26690345

so clearly the UEFI OptionROM of my GT 740 is not being loaded by the MacPro5,1s EFI for some reason

The GOP rom loads, but we've been unable to get it to drive a display.

I'm a little confused, you say the GOP rom loads, but it doesn't show up in devices in the shell?

Could be pulling a disappearing act because of the GOP rom, I've seen this with FCode roms before.

Maybe that is what we are seeing with the RX580 and the 5,1?

 

[LightBulbFun]

I should also try sticking my GT 120 in and switching the Radeon HD 7950 to PC UEFI mode and see what that does...

Yes, try that, see if the GOP rom loads, and if the card pulls the disappearing act in devices from the shell.

Cr*p typo sorry I meant to say "does not show up in the drivers list at all" either the UEFI OptionROM of the GT 740 refuses to load on the MacPro EFI or the MacPro EFI wont load it for some reason...

(the drivers listing picture, is of my MP5,1 with its Radeon HD 7950 Mac flashed card installed)

 

[LightBulbFun]

I did a bit more testing this time with an Apple GT 120 and my Radeon HD 7950 in PC-UEFI mode

sadly clover did not display anything on the HD 7950, it only displayed on the GT 120

but as a side note, I booted just a EFI shell via the Boot picker from a USB stick while i had the GT 120 and HD 7950 in (ie for this I did NOT boot clover in any way)

and I did notice that the UEFI VBIOS of the HD 7950 does seem to get loaded, in that theres an extra <unknown> entry under "AGP driver" with the HD 7950 in PC UEFI mode

[Forbidden Era]

from a brief google it seems my 560ti might be able to be GOP'd so I might have to try this!

 

[DearthnVader]

Ok, I think I've figured out why the 5,1 gets no GOP boot screen with our custom code, but the 3,1 does.

The Apple Graphics Policy driver loads for GOP cards on the 3,1, but it doesn't on the 5,1, it only loads for UGA cards.

The fix maybe as simple as replacing the AGP Driver in the 5,1 firmware with the AGP Driver from the 3,1, or another Mac that supports GOP.

You won't get boot screens by just replacing that driver, you'll still need some custom code like our rEFInd/nEXt Loader/Clover with GOP enabled.

I don't have a 4,1/5,1 so some brave person will have to try it, preferably someone with a MAT Card.

Any takers?

Call for your help.

Are you interested in helping us to mod the 5,1 BootROM and test if this can allow our 5,1 shows boot screen by UEFI GOP?

For this mod, I think we really need someone can hardware flash the logic board as escape route.

I am ready for testing with a MATT card installed just need some instructions.

Meanwhile for anybody who has SIP enabled, no EFI card and all PCIe slots occupied there is a solution:

sudo nvram "recovery-boot-mode=unused" && sudo reboot recovery

This boots straight into recovery so you can disable SIP

I though SIP protected nvram, maybe only parts of it?

It would be best to load the AGP Driver from a shell first, I know you have a MATT card, but if the driver isn't compatible with the 5,1's firmware it won't do us any good to inject it.

Copy the BOOTX64.efi to your EFI boot partition, in the folder /EFI/BOOT/, if you don't have to BOOT folder, just create one.

Copy the AppleAGP.efi to the root of your EFI partition.

Bless the shell, i.e. BOOTX64.efi:

sudo bless --mount /Volumes/EFI --setboot --file /Volumes/EFI/EFI/BOOT/BOOTX64.efi --nextonly --verbose

Reboot to the shell:

Find you mapped file system:

fs0:
ls

If you don't see the AppleAGP.efi, try fs1: fs2: ect...

Once you find the file:

load AppleAGP.efi
drivers > drivers.txt

Upload the drivers.txt file, it's will be on the same refi partition as the AppleAGP.efi.

PS: Had to add .txt to the end of the two files to attach them here, so remove that before use.

I'm pretty busy with work for at least a week, since @startergo is already helping with the tests…

I'll be watching here when I have free time.

Looks good, the driver loaded, so I think it will be compatible with the 5,1 firmware.

First, download this version of UEFITool:
UEFIPatch_0.25.0_mac.zip 1.38 MB

Save you firmware, and open it in UEFITool, you can dump your Firmware with @dosdude1 ROMTool.

ROMTool.zip

In UEFITool File>Search chose GUID and search for:

8A107CC5-DCDA-4FB7-A272-4243B41AFBFE

Expand that GUID out until you see PE32 image section.

Right click on it and choose replace body. Open the AppleAGP.efi, then File>save image file.

That should be it, now just flash that firmware.

Reboot to a shell as we did before, or if you have a GOP card, install that with your GT120 so we can see if the driver loads for both cards.

If the AGP driver doesn't break anything, and you get to the shell on your GT120, upload a drivers.txt file for us.

EDIT:Just noticed you have a Radeon GOP card, but you need to flash a valid ROM back to it, you must have edited the VBios protected tables. That won't work for GOP boot screens, as the driver never links to the device>INVALID.
