1.
IMPORTANT : Shut down your cMP label the BIOS switch like this . .
Left switch position WIN Right switch position Mac.
2.
Boot into Windows / GPUZ and download and backup your current rom to a USB stick
3.
The most important thing is to first look in System Information under Graphics/Displays and find your "Device I.D."
The reference 7950's device I.D. is 679a
4.
Download "bundle" from the Netkas thread and put it in your Users/wulai/ folder
I think that if you are a novice . .then read the whole thread and copy the most relevant information.
===========================================================
This is only an example script : Change the BOLD TYPE to reflect that the rom creation is happening on YOUR computer
through the contents of your BUNDLE folder.
Tom-Joness-Mac-Pro:bundle tomjones$ ./makerom.sh --efifile=7950mac.efi --romfile=efiromheader_7950.rom --originalrom=7950.rom --devid=679a
It's been two years since I flashed my 7950 . .hopefully no mistakes in any of the above info.

Thank you very much, I am novice, I don’t even know what software to use.
How to convert your original rom to an EFI
Thank you, I have succeeded, but windows10 can't enter.

Thank you for the link provided, I seem to have succeeded.but windows10 can't enter.
If your Windows 10 is in UEFI mode, that’s normal. The EFI UGA of the 7950 is not compatible to the Windows UEFI.
Most like that's legacy Windows, not UEFI Windows.
I am quite sure HD7950's Mac EFI will lead you to BSOD if you use that to boot UEFI Win 7, 8, and 10.
[doublepost=1535037622][/doublepost]Same as crossfire.
Legacy / UEFI HD7950 ROM can use corssfire.
If boot from Mac EFI HD7950 ROM, you will hit BSOD once boot to desktop (with crossfire enabled).
yes，Mac efi 7950 lead to windows10 BSOD。 Is there any way to install windows10 normally?
1) Burn a Win 10 installation disc
2) hold C to boot to the disc
3) install Windows 10
This will install Windows 10 in legacy mode. And not affected by the 7950 Mac EFI.
My EFi'ed 7850's BIOS switch is set to RIGHT position ( EFI ). I just booted both Win 7 & Win 8,1 from their own dedicated HDD's with no BSOD.
Selected from the boot screen Win start up displays a black screen with a flashing cursor for up to one minute. . then . . boots into Windows with no problems

If you don't mind, can you open Terminal, enter

Martin, I removed both of the ( hot ) SATA II Win7 & Win 8,1 spinner HD's immediately after doing the test.
I just don't need to use Windows at all lately.
Also, It's so hot here in Japan today that I removed the 7950 and put in my trusty 5870 until the weather cools down a bit. . but . .I did do the tests with the BIOS switch in the EFI position on the 7950.
I'll do the test again at the end of this heatwave and post results for you.
( I'm actually quite surprised at how well the 5870 handles Hi Sierra 10.13.6 ! )

At the opposite side of that harbour.

No rush, I just want to confirm your Windows is installed in UEFI mode.
I own the Mac HD5870. This Mac Pro is for work. It is currently upgraded to HD7950. It is mainly used for video editing. Is it better? Another Mac Pro for gaming at home (PUBG), can I recommend a graphics card?Martin, I removed both of the ( hot ) SATA II Win7 & Win 8,1 spinner HD's immediately after doing the test.
