Well I finally managed it, and you gonna want to slap me sooooo hard when you find out what I was doing wrong, I didn't have Java installed!
And the reason was these two,
if you forward to 5:34 you see they get the Java error so I stupidly assumed this was normal, NO it is not normal, I installed Java ran the script according to instructions and a bundle from MIKX as below
./makerom.sh --efifile=
7970mac.efi --romfile=efiromheader_
7970.rom --originalrom=cardname.rom --devid=6798
Flashed it and now I have dual screens AND boot screen just like I wanted and no extra power needed from SATA, again thank you all you for your help and thank you for your patience (even though it probably ran out in the end)
And I also attached the photo of the card you wanted, and also the original and modded roms if anyone is interested (use at your own risk)
😉
You will be pleased to hear I have replaced the hideous spray painted cover and fans with parts from a dead card I found on eBay.
