Boot screen flash service for Apple Mac Pro video card USA

Description

Service to flash your video card
to allow a boot screen for your Apple Mac Pro.
This will allow your video card to see the boot screen in the initial boot-up process.
Simply mail in your video card, I will flash it, and mail it back promptly. I will send you the mailing address after purchase.
This works best with these video cards:
Sapphire R9 280X
Gigabyte R9 280X
HD 7970
HD 7950
HIS HD 7970
HIS HD 7950
If you have a different video card than what is stated above please contact me first and we can verify if it's possible or not. Although we know how to add a boot-screen to RX 580 or newer GPU's, we are not currently doing so since the process involves removing the ROM and soldering on a new one. However, we can provide a software based solution that works really well and doesn't involve you mailing your video card to us (it can all be done via email).
We also flash Titan Ridge and Alpine Ridge Thunderbolt 3 cards as well for macOS - here are the links:
