Looking for a graphic card with boot

A quick test shows no bootscreen. I did…

1) clone primary SSD to backup HDD (tested bootable)

2) install cover (all default setting, GPU is HD7950)

3) select HDD to boot, restart

4) hear the chime, but black screen only. HOWEVER, all USB 3.0 drives work (card reader / HDD enclosure LED shows that all SD cards / HDDs are mounted). That's just few seconds after the chime, so, 100% not load to OS desktop yet. Something properly initialise the USB 3.0 card (KT4004).

5) no loading sound from HDD, the computer seems waiting for something (may be cover is actually there but I just can't see), so, I press Enter (assume it's pointing to the default HDD).

6) continue to boot, and then confirmed that's boot from the backup HDD.

So, the good news is.

A) it won't kill anything

B) USB 3.0 may be bootable!!!

But I need more time to figure out if I can make cover properly initialise the GPU.

Try putting the relevant graphic kexts into the relevant folder in Clover for your version of macOS.

I don't know how this procedure would work with AMD/ATI. My guess is that, Clover should be able to initialize the video card. Secondly, since we don't have to do anything special to activate the AMD/ATI drivers, it should just work. Again, this is all speculation on my part...

Yes, if you don't change any settings, I think that Clover won't do anything and will just act as a boot loader that you can use to select whatever operating systems you have on your system. Example:

looks good

Hmm. Yes, it does sound like Clover is loaded but it's not initializing the video card. Did you choose Legacy when installing clover?

Unfortunately, I have no experience with AMD/ATI video cards with any recent version of macOS...

Maybe you can try setting the default boot volume with Clover Configurator and then press the Return key when you believe the Clover boot loader has loaded to see if booting macOS will get you video.

No 100%, but this is what I did. That 2 ticks are default config, no other ticks. And the 1st item "UEFI booting only" remain uncheck, so, I think it means legacy also supported.

When I try to use cover configurator, I get this warning. Should I duplicate the plist file, mod it, and than fix the permission by myself? (This warning appear regardless if I mount the EFI partition or not)

Thanks for your suggestion, can you tell me more details on how to do it? Cover is more complicated than I expected.

pastrychef · Nov 22, 2016

I think "Install Clover in the ESP" may need to be set.

For the config.plist, I've never encountered that, i would duplicate because I don't know the correct permissions to set it to.

Yes, that ESP fix the permission problem.

Fl0r!an · Nov 23, 2016

A simple UEFI install of Clover with no additional configuration should work. AMD cards don't need any special configuration, just leave Inject / Ati to False, no additional boot flags.

I'm not sure if you can select Clover as default boot volume from the system pref pane or if it has to be blessed from the Terminal. Can't test that locally because my MacPro has a broken NVRAM.

h9826790, any update on using Clover?

I stopped the study after only a few try, because it require more knowledge than I expect. I may resume that study, but there are many other things for me has higher priority at this moment.

Anyway, no definite conclusion yet, however, from my tests. It seems clover can make my USB 3.0 card work before macOS kick in. So, the hope is still there.

I found this thread by chance and thought it looked interesting so thought I'd give this a try. Mac Pro 5.1 GTX980 pc nvidia card hence no boot screen, have plenty of drives to clone and experiment with however…

I fell at the first hurdle, couldn't even get the installer to work as I get an error message: Package is incompatible with this version of OS X.

From the google research I've done it looks like it is to do with the rootless/SIP protection introduced in this version of the OS. From what I understand, either an updated installer is required, or to disable SIP before doing the install which involves booting into recovery mode and punching in some terminal commands. All well and good, but I don't get a boot screen, so bit of a catch-22.

I've opened a ticket on their site so will see what comes of it. Just thought I'd put it out there…

I thought I've read that recovery mode works with unflashed cards. I think h9826790 has done this.

Correct, but that should be only applicable to the card that has native Apple driver. Since 980 require web driver to work, and there is no web driver avail in the recovery partition. So, I will say that's a no go for Maxwell card. Even worse, from memory, at least one member reported that even a flashed Maxwell card can't access the recovery partition in Sierra now, but I cannot test this by myself.

1nfr4r3d · Mar 2, 2017

hmmm, OS X does have some default drivers for this card albeit not as well optimised as the NVidia drivers- there's a control panel in preferences which lets you switch between the 2.

I suppose the only way is to test it out, will let you know what happens…

Fl0r!an · Mar 2, 2017

There are no "default drivers" in OS X for this GPU, you won't see anything without the WebDrivers with an unflashed Maxwell card.

It might be possible to copy the WebDriver .kexts into the Recovery partition, never tried to do this though.

1nfr4r3d · Mar 3, 2017

You may be right. I tried to reboot in recovery mode but just got a black screen and upon restart an error message and log hinting at a kernel panic (I think), I've include it below just for reference in case you guys understand it.

You'd have to talk me thought the copying of kext files (from/to) though Florian, i can give it a go on my spare drive so no harm done if it cracks out.

Finally have more time to test the "cover theory".

I managed to boot to cover (automatically). However, can't get the boot screen (without Mac EFI).

Also, when I boot to cover, I go to Options -> graphic injector, swtich on InjectATI, load video BIOS, etc. And then use "return" go back to the main menu.

However, once I restart the computer, those options back to the OFF position.

Anyone know what's wrong?

Also, select Bootcamp partition from cover will cause the the computer hang straight away. Shows black screen with a little white square in the centre (the square is same size as the Apple boot logo).

Choosing Windows as boot drive from system preference, or option boot to Windows, can boot to Windows (totally bypass cover).

I don't think you need to activate any of the options. On a real Mac, it should only need to serve as a GUI for you to select the OS of your choice. Once you've selected, the operating systems should load as normal.

With the stock options.

Cover only shows up when boot from the Mac EFI ROM (R9 280).

With PC VBIOS, only black screen. But I can sure cover is there, just nothing to display. Auto count down 5s to last boot drive works. Also, if I try to blindly navigate (disable the auto count down). I can shut down the Mac by short press power buttons.

pastrychef · Apr 19, 2017

Hmm... I think we need to wait for Fl0r!an to share his experiences...

Also, are you using an AMD or Nvidia card for testing non-EFI?

Are you sure you installed Clover in Legacy Mode?

In Legacy Mode, you Mac should boot via the Bios Compatibility Layer or CSM. The CSM should load the vbios from you PC card, and you should get video on the Clover Boot screen.

I have absolutely no idea about this. Will need more time to study about that. Anyway, million thanks for your input. That's a very clear direction for me to go. Will report further once I can confirm that my installation is in Legacy mode.

Is the Disk you are installing Clover to a Hybrid GPT disk, i.e. did you install Windows via BootCamp on it?

I think, but can't confirm, that to install Clover in Legacy Mode you need to install boot0af or boot0ss, but I'm unclear as to installing to the ESP.

For me, on my Hackintoch, I have a Bios Motherboard, I use a MBR formatted USB stick with one HFS+ partition. I must choose Install boot0af to MBR and CloverEFI 64-bits BiosBlockIO.

The BiosBlockIO is only necessary for some Motherboards, likely not for the Mac Pro. I have chameleon installed my HD for booting 10.6.8 and 10.9.x. I had trouble with installing Clover to my HD, I never figured out the right combo.

I have a pure GPT disk, as I need more than 4 partitions.

Code:

/dev/disk1 (internal, physical):

I have multiple copies of OS X, and some OS X installers, Linux in EFI mode, and Windows 8.1 installed in EFI mode.

It's unclear to me, if you have Windows installed in BootCamp on a Hybrid GPT disk, if writing boot0af to the MBR with break your Windows install, Clover maybe able to boot it, or you may have to re-install Windows in EFI Mode, via Clover. It requires creating a USB install disk for Windows and copying a special boot file to it, the default boot file won't work.

Cover is installed on a HDD that with single HFS+ partition (not counting the EFI partition), MacOS 10.12.4 clone from my primary boot drive every morning (by CCC). No recovery partition on that particular HDD.

Never install Windows on this HDD. I tested it with the Windows SSD (SATA, connected in upper optical bay) connected or disconnected, same result.

The HDD should be pure GPT.

It the very first time I know something call boot0af and boot0ss. So, may be that's the problem.

boot0af:

Code:

Used for BIOS booting on BIOS motherboards.
boot0af (boot0 Active First) bootloader tries to boot the active partition defined in MBR. If there is no active partition, it will try to boot the first EFI/FAT32/HFS partition (defined in the MBR and then the GPT) with a valid PBR signature.
This choice will set the selected HFS/FAT32 partition status byte to active in the MBR.

boot0ss:

Code:

Used for BIOS booting on BIOS motherboards.
boot0ss (boot0 Signature Scanning) bootloader tries to boot the first EFI/FAT32/HFS partition (defined in the MBR and then the GPT) with a valid PBR signature. If no partition is found it will try to boot the active partition defined in MBR.
This bootloader is a good choice when you have Windows installed on the same disk because Windows wants to have its partition active.
This choice will NOT set the partition status byte to active in the MBR.

I would think you need the boot0af, but it's unclear to me if you pure GPT/GUID disk has any sort of Master Boot Record to write it too.

Looking for a graphic card with boot
