This thread would do well to become a WikiPost. Doing so would enable you as well as others to add the stock iMac vBIOS for other versions of early Intel iMacs to be added.

Hi there. I have a brand new AMD RADEON PRO wx4150 4gb. The seller put HP vBios on the card even though it is a Dell green card. He said for better compatibility. I could boot into my MacOS 13.6 using Opencore Legacy patcher 0.6.8. On startup there is no initial white screen and if you hold down alt or option on sartup the computer freezes and stops.

So i tried on Bootcamp Windows 10 to force flash a Dell vBios that I got from Techpower up site and used some command lines then I restarted and blackscreen. I can hear it's booted into Bootcamp windows 10 as the fans are running with Macs Fan Control. My question is why was the original vBios not 100% and second why has the Dell vBios failed. Must I get my vBios that is suited more for a mac. I used AMDVBFlash as well. I really need help.

My iMac is a mid 2010, (11,3) with 12 GB Ram, Core i7 870 CPU with an SSD Drive.
