Thank you.
You are very welcome.
I did this and will attach the file below; just want to make sure I didn’t mess anything up.
Looks good to go, note that you can’t use Q-flash to flash the modified BIOS and will need to use EFIflash from a bootable USB stick.
I had to modify both 906ED and 906EA since the tool wouldn’t change the microcodes if I just modified 906ED.
I have never changed just one microcode - good to know.
You mentioned earlier that Gigabyte didn’t lock the FD on Z390, but I see in the tool it states it is locked. Is this only for this particular BIOS version?
The bit may be set but the protection was not enabled when the BIOS was created.
You can always set it to unlocked with CoffeeTime if it visually annoys you.
