I am too!!!! I hope its OK to ask this-- how did you learn about all this low level code stuff for operating systems? Just by doing it for a long time and reading forums? Do you have any idiot's guide stuff to how this all works? I'm an amateur coder, mostly for creative projects, but this has...

Ok! I couldn't get my hands on a monitor with a display port input but I was able to obtain three display port to vga adapters and they work!!!!!!!!!!!!!!!!!! I'm doing a happy dance!!!!!!!!!!!!!!!!! Ed thank you thank you thank you a million times!!!!!!!

Hey Ed. Thanks so much anyway for your help. I learned a ton! Going to continue to research best I can while I try to find a way to get access to a monitor with a DP input. I'll let you know if I find anything else that works!

Hi Ed. Thank you so much! Unfortunately, I have the exact same issues including the same errors in the boot log and the console log. Any ideas?

Ah ok. Sorry for the misunderstanding. Thank you for sharing the link! Attached is the ioreg file. Thank you again for all your help!

Ok I finally was able to figure out which PCI slot the graphics card is in. According to the Dell manual its PCI_E4

Hi Ed, I backed up my clover folder and replaced it with the one you provided. It still goes black, but I'm feeling hopeful. Attached is the IOReg and Hackintool's ACPI dump. Thank you thank you thank you!

Ah ok - I was experimenting with updating clover and I had been running r5119 but I just tried updating to the most recent version. I will revert back. I have a theory that I'm exploring which is that Westmere CPUs don't have iGPU features. Whatevergreen seems to rely on it. The SMBIOS that I'm...

Here is a screenshot of the console log running with blank screens-

There are a bunch more errors related to the graphics so I am attaching the full kernel log as well as the boot log.

Hi Ed. Thank you for this! I tried one at a time and both together and none of them worked (one of the files you shared was .dml so I used MaciASL to recompile it into a .aml file before adding to my EFI partition. Thanks for sharing these tools with me. I replaced the Whatevergreen kernel...

Hi Ed! Thanks again for your suggestions! I have gotten rid of the HDMI to VGA monitor and I am just using the single monitor with just a single DVI-D cable connected-- no adapters. I added the file you supplied to the folder /EFI/EFI/Clover/ACPI/Patched/ Is that all that I have to do to...

It also shows up as the graphics card for the OS so something is working most of the way. Just not all of the way. Since this machine doesn't have an iGPU, I'm hesitant to try to mess with frame buffers...

Update into the void I connected a second monitor - now I have HDMI and DVI-D outputs and the monitors don't go to sleep as though they are disconnected. They stay awake but just show a black screen. When I screen share into the machine, it shows two screens instead of one.

I finally figured out how to get a copy of the boot log. Long day.

Update: I have had no luck with the graphics card although I did boot from it on my MBP and I was able to enable screen sharing. The good news is that the computer boots all the way and I am able to screen share into it with no issues. I just can't use any of the video card outputs.... I saw in...

Also, just to be clear, is mounting the EFI partition, deleting the old WEG and Lilu kernel extensions and then replacing them with the ones you provided a correct way to update them? Trying to make sure that I covered all the bases.

Update: The last message that verbose mode startup writes is: "IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0"

Ok Ed, I tried your suggestions and I still am unable to get past the black screen (though I am learning a lot from this). My new SMBIOS is iMacPro1,1 (used clover configurator to take care of all the values in that menu) boot arguments are: dart=0 shikivga=128 per the chart in the whatevergreen...

Hi Ed. Thanks so much for your response! Unfortunately, I don't think I have an option in my bios for the Intel iGPU. It's that super old American Megatrends Blue CMOS Setup utility so I will try using an older SMBIOS as you recommended with the noted config adjustments and boot arguments and...
