Boot screen with Sapphire Pulse RX 580?

[TECK]

Do we have a flash method to enable boot screens on a Sapphire Pulse RX 580 8GB? I'm installing this card into my Mac Pro 4.1 firmware flashed.

No.

If you willing to join this thread and be one of the beta tester, then you may be the 1st one on the world that has boot screen on a 4,1 with the RX580.
