Vega 64 Boot Screen

[MarkKiss]

Hi,

is there any way how to modify / install VEGA 64 in Mac Pro 5.1 to be able see Boot Screen

I want to be able swap between OSX / BootCamp Windows
I want to be able reinstall OSX Mojave (Metal GPU is required)

I have original HD 5770

Or if is better to sell VEGA and BUY 1080 / 1080Ti ?

Thanks for any suggestion

No bootscreen, unfortunately.

You can change your start up disk in MacOS to boot Windows.

NO.

I want to be able swap between OSX / BootCamp Windows

You can do that natively with just the Vega, no boot screen is required for the whole process.

1080Ti may be more powerful for some apps. But definitely won't make your life easier if you want to install 10.14.

So I can plug USB with Mojave and install even without boot screen? Installation will show?

Yes the installation will show, you will not have the initial boot screens

I can confirm this as well eventhough I did it with High Sierra (which I reinstalled a couple days ago on my 5,1 with a newly bought RX560). The Apple logo and installation progress bar were visible.

If you don't mind a non-stock boot loader you can use the CSM layer to get boot screens with Clover Legacy.

No Idea. I just moving from iMac 2015 to Mac Pro (iMac simple does not have enough power) Can you share more info about Clover Legacy?

Thanks I will have look on that

Clover seems to have a bug where it doesn't write the first stage boot loader every time, I've sort of had mixed results with it.

Blessing the disk where you install Clover for legacy boot enables Apple's CSM( Aka Legacy Bios Compatibility layer ).

It's this CSM that enables the legacy Video Bios of the graphics card. However if the Clover installer doesn't write the first stage boot loader you'll ether end up with a screen that says "no bootable disks......" or it will boot any legacy OS's you have install ( Windows/Linux ).

Unfortunately, there doesn't seem to be a whole lot of rhyme or reason to how to get the clover installer to properly write the first stage boot loader to the Master Boot Record of your disk, I find that sometimes using an older Clover installer first, then the newest Clover installer works, sometimes.

If you booted from the NVMe when you install Clover, then most likely you installed Clover on the NVMe (may be the inside the NVMe's EFI partition).

Anyway, PRAM reset can't bring you back to the normal macOS?

How are you powering the Vega? I have a 56 I’d like to use

I have a Radeon Vega 64 and I followed the Pixlas Mod online - https://thehouseofmoth.com/mac-pro-pixlas-mod/. I bought the correct cable they suggested and fitted it all within about 1 hour according to their instructions. It helps to have a laptop and an iPad, I can look at either of those to follow along whilst upgrading the Mac Pro. The Mac Pro has a 980 watt power supply which will work flawlessly to power the card with no issues, along with everything else installed. Mine I have owned since I bought it new in 2009. I recently (2019) bought two lidded X5690's (much cheaper than de-lidded cpu's), used a small vice ($8 at a hardware store) to knock the top of the processor lids off and installed with no issues and checked temperature of these processors - sitting at around 54 - 60 degrees under load. So it's had the Pixlas Mod, installed an NVME 1TB card, installed a Blu-ray drive a while ago as another source for backup and ripping. I have it setup to dual boot Windows for gaming as well. I have a Blackmagic Intensity Pro as well as a 4 port USB 3.1 card. All hardware works cross platform flawlessly. I have essentially filled up all my slots. I installed 64GB of ram as well. If you need a detailed breakdown of how I did it, I can write something up more detailed in the forums.

I would love to read more. Can you send me what you did please?

MacVidCards in Poland can flash the Vega 56 and 64 to have a bootscreen:

Don't bother with a flashed card, Flashed cards are a thing of the past,
just install OpenCore, read this Thread.
https://forums.macrumors.com/threads/opencore-on-the-mac-pro.2207814/

open core supports a boot screen Even for UEFI cards.

Then decide if you wont to risk spending a pile of money on a flashed card that may just crash on you,
like the MSI RX Vega 56 card a purchased from MacVidCards in the USA,
and he will not respond to my emails about it,
its been 4 months and 3 attempts to contact David about it and yet still no response.

"F" MacVidCards save your money buy a UN flashed UEFI PC card then install OpenCore.

This is the Pre-configured openCore i used on my 2012 cMP and it worked a treat.

It's a fact that there are lots of posts about (serious) issues with MVC USA.

TBH I've bought several flashed cards from MVC Europe over the years and never ever had any problem at all.
I've also send cards in to get them flashed; same experience: no problems at all.
Excellent communication, fast shipping and decent prices.
My recommendation is based on my own experiences.

I'd leave it up to anyone if you prefer to install OC or are willing to spend not " a pile of money" , but a small price somewhere ~ €80,- up to €150,- for the flashing service....
Obviously, this is an option for people in Europe only...

I'm in Australia so Euro V AU dollars makes a big difference in price.

Since flashed cards are on their way out now due OpenCore coming into being,
it makes sense to just go with a PC UEFI card, and use OpenCore as your OS boot loader,
since it supports UEFI Bios cards,

Save yourself $80.00 to $150.00 by just spending 10 minutes installing OpenCore,
and never have to chase around for flashed cards, or flashing services ever again.

Seriously it only took me 10 minutes to install the config i used,
and that included reading the instructions on how to install OpenCore.

Also OpenCore has NVRam protection for people like my self who have a UEFI Windows 10 installation,
so the Windows boot.efi can't brick your logic boards NVRam.

After a little web searching i found a flashing tutorial that informed me that my vid card has a dual bios,
1 for flashing,
And a protected factory UEFI bios that can not be flashed,
swapping between the two is as simple quite literally as flicking a switch on the card,
so that saved me having to re-flash the card to fix the corrupted EFI bios for mac that david have added to the card.

I see your point of view and agree with you.

There are people out there though , that prefer to keep all installed OS vanilla. OS natively installed.
I imagine that reading the OC thread might get some overwhelmed with all details and steps to take, resulting in headaches about how to keep it up and running....

I don't know if you have read up on OpenCore, its like ReFind, it sits in the EFI partition,
No OS changes at all.
