Intel HD4000 and Radeon R7 250x (HD7000) simultaneously

Yes, with a GPRO 4200, four Mini-DisplayPort. I also have a GPRO 6200 with six Mini-DisplayPort. I can also use this one, it has the same ID.

I have good news.

In my EFI partition I was using Clover 5161. In the Clover options menu in the graphics section, my graphics card was listed as 'AMD unknown model'. I tested older versions of Clover, and version 5155 showed it as 'AMD Radeon 8800M series'. I now could use the InjectATI option without the X64 Exception.

I'm still not sure if Mojave graphics acceleration is fully enabled, but I tested the game Plasma Pong and has a locked 59 Hz like the monitor.

I added in Devices/Properties the name of my graphics card and it's now correctly shown in Mavericks and Mojave. Only the CPU type is shown wrong, 700 MHz Intel Core i7. But that can be fixed.

That is great. Your profile indicates you're using macOS Mojave. Can you confirm that?

Attach the EFI to check!

I'm switching between Mavericks and Mojave. I'm doing the most work using Preview - but the version from Snow Leopard. I've found no replacement graphics tool which is so easy to work with. But the newer versions are unuseable because the paste the clipboard image centered.

Mojave is nearly finished, I now want to complete the icons for the applications I've installed.

The attachment contains my EFI folder. The dsdt.aml is only for avoiding the unknown CPU 0x3a error. The config file is written with Clover Configurator 5.8.0.0.

I've changed my computer settings from iMac13,2 to MacPro6,1. That should be the best setting for Monterey on Ivy Bridge. Monterey is starting to boot, but crashes at AppleAHCIPort.kext. My 7 series SATA controller ID 0x1E02 is existing.

Incomplete EFI attached. Mount your ESP and attach the working copy of the EFI that you use to boot.

What else do you need? I have no kexts in my EFI partition.

Remember, it's Clover on Legacy BIOS, not OpenCore on UEFI.
These are the BIOS drivers I have installed:

AppleAPFS.efi
EnglishDxe.efi
HFSPlus.efi
OpenRuntime.efi
XhciDxe.efi

In the attachment is the graphics card ROM.
