I'm losing options what to do - SMC Reset? Not workingĪpple's Mac Pro gets the most powerful AMD GPU ever with a whopping 120CUs and 64GB VRAMĪMD today has released its most powerful workstation GPU ever with the new Radeon PRO W6800X Duo. Then in El Capitan copied paste those lines and 'python' fix - then 'cooked' BIOS installed by WinATI (not DOS ATI) - I remember in 6870 I was doing everything with DOS ATI - but again - I cannot believe that should do a difference. The only one crazy thing what comes to my mind why they not showing boot logo is that - I dumped BIOS without Windows drives - but cannot believe it that. I'm struggling with flashing my Radeons to see Apple LogoĪt beginning I want to say I successfully managed to flash XFX 6870 (to see Apple boot logo) so I thought I know what I'm doingĪt this moment I ended up with working Sapphire Vapor-X 5770 and Vapor-X 5850 - in macOS they are displayed as 57 (5870 because I flashed it with 5870 ROM as there is no 5850 ROM) - but anywhere there is no Apple Logo I've tried all display ports and HDMI.Įverything I was doing with one Mac Pro 2008 with 2 HDD - one with Windows other with El Capitan (to avoid problem with choosing boot choose as no 'Apple Logo')
