MP 1,1-5,1 About to try EnableGOP - can someone check my Rom dumps?

[TKOS7]

Hi,

I have the following system currently:

Mac Pro 5,1 (2012) with:

Single tray 3.46GHz X5690
24GB DDR3
Sapphire RX580

OCLP Monterey 12.7.6 installed on an NVME drive (blessed)
Mojave installed in an SSD

I would like to inject EnableGOP to get a native boot screen. After research and following some videos, so far I have:

Taken out the Mojave Drive to leave just the Opencore drive
Disabled SIP
Downloaded Macshrauber's Rom dump app, EnableGop_1.4.ffs and DXEInject.zip
Successfully inserted EnableGop into a copy of my BootRom

So I'm ready to flash the new bootrom. I just thought I'd double check as I'm seeing some slightly odd looking stuff on the rom dump - notably the old Bootblock and a Kernel Panic. Does this Rom look ok to flash? Or would it be better to do this process using the Mojave install instead of the open core Monterey install?

Current ROM;

All entries stored in nvram remain with the mod. After a multiple nvram reset entries should be gone.
You may also rebuild the bootrom on your own, this will empty the nvram stream totally: https://forums.macrumors.com/thread...-4-1-5-1-bootrom-with-template-files.2437082/

Should I do that before flashing this rom? Or will it be ok as is?

 

[Borowski]

I can't judge this without having dumps to 100% guaranteed, but the tool can recognize most of the common problems and if you did GOP enabling injection mod exactly as described, this should be safe.

Just flashed it. Worked great - now I have a boot picker! Thanks for the help.
