Hello,
I have a Mac pro 3,1 that has a dual boot of Windows 7 and mac OS Catalina
I recently got a Sapphire AMD radeon 7950
it has 2 mini displayports a fullsize HDMI and a DVI port
Currently, netkas forum seems to be down but I had downloaded the script files before it went down. I ran it and I still don't get boot screens...I cant test displayport as my monitor is HDMI or VGA (so I have to use a DVI to vga adapter) I tried both ports nothing. I have tried other radeon 7950 roms and some of them I was able to get bootscreen..but only on the DVI port never the HDMI.
when I was using that mac 7950 rom I can see the apple logo and the progress bar it gets halfway and then I lose video signal completely (on dvi I get no video at all on HDMI). it looks like to me that Apple dropped analog video ports in this version of OSX (can somebody confirm) as that would make sense why it drops video signal while it boots
I am at a total loss I have tried about 7 different roms 2 different macs to run netkas script. dumped with ATIflash vs darwindumper. I have posted my backup.rom this is a dump from ATI flash tool.
Can somebody get bootscreens+working Catalina on either HDMI or DVI?
I will note that this video card boots Windows 7 and Catalina fine if it is running a stock vbios. I just dont get bootscreens in OSX until the logon screen. so I don't think there is anything wrong with the video card itself
-Thanks!
