Hi everybody, I know it's gonna give some people here who don't like what I'm doing now, but I also know that there will be someone who will benefit from it. It all started with an order at MacVidCards to flash my GTX 1070 8GB graphics card (MSI Brand, 3x DP, 1x HDMI, 1x DVI). Everything worked fine, full 4K resolution of the boot screen on all ports, great performance and no problems until Apple released the APFS supported bootrom update for the cMP 5,1 which unfortunately interfered with the MVC EFI ROM (bootdiag messages at bootscreen and slow boot times while enumerating apfs volumes - the more apfs volumes, the more boot delay). If MVC hadn't behaved so customer unoriented and sent me a correction of the EFI BIOS to flash by myself, it wouldn't have been a problem. On the contrary, you should probably send the card in again to flash, and pay the full price again, all by having the solution already finished for the GTX 1070 TI. But although I had sent several mails, as well as blog entries on their homepage, I didn't get any answer from them. I was hoping to get some but they simply left me in the shade. I find this handling of a paying customer very embarrassing, and out of pure anger I would like to post the MVC Mac EFI BIOS for my GTX 1070 8GB here, maybe someone can help me remove the annoying boot debug messages and incorporate the DP1.4 patch, if MacVidCards doesn't feel it necessary. Or, somene can live with that stupid debug lines and no working dp1.4, and can use it on its GTX 1070 8GB. PLEASE, DO NOT INSTALL THE EFI BIOS IF YOU DO NOT HAVE THE POSSIBILITY TO FLICKER A SWITCH FOR RECOVERY BIOS MODE. For anyone else, it is my interest to help people which have the same issues than me, (or no bootscreen at all) without messing with such a*****es like MVC. I don't care at all whether someone finds this justified or not. == EDITED == Removed the rom because not sure that it is complete.
