Resolved yeton 7970 mac efi？

[xyzliu123]

After making MAC EFI ROM in the public version of Yeton 7970, there was no Startup menu and black screen. I flash MSI 280X MAC EFI rom, there is a startup menu. However, the frequency of 7970 is 925 mhz, and that of MS 280 is 1020 MHZ. I feels that the video card is overheated. Who can help me to make a YETON 7970 MACEFI rom? Thank you! Attached is the original ROM of YETON 7970.

From the output of running makerom.sh it looks like it requires elevated permissions. Have you tried to run it with sudo?

sudo ./makerom.sh

There do not appear to be any differences between the two files. What is on line 42 of makerom.sh can you attach so we can take a look.

Try

Am I mistaken in thinking that a thread marked "Resolved" is no longer a problem?
