MP 1,1-5,1 MacPro5,1: BootROM thread | 144.0.0.0.0

[tsialex]

Hi Alex,

Trying to update an old MacPro 5,1 (mid 2010) running under Mojave and a Sapphire RX580 GPU, the Boot Rom Dump created with MacSchrauber’s tool shows the following errors :

- Length of 2nd VSS Store is wrong (FF FF FF FF)
- VSS2 (Formatted) (VSS2 header problem), found 38 variables (38 valid)

I'd like to add Enable_GOP but I'm afraid of these error before trying that... Can you help me to clean/reconstruct the Rom and send me by PM instructions/files required/service fee/turnaround time?

Sure, PM sent. Btw, I always send two images, one standard image exactly like Apple and another one with EnableGopv1_4 already injected.

Hi Alex,

I need help with my bootrom 144. My 2010 5.1 mac pro works very well but MacSchrauber’s tool detects crc errrors e give me the message that the firmware is inconsistent. all the other values are ok. i have an XfX Rx580 not flashed and work nice. i'd like to enable Gop but but i have fear to brick my Mac Pro flashing gop with these crc errors.
Can you help me with reconstuction?
Thanks.

If you have a backup before the mess above, you surely can flash it back, but seems your backup is from 141.0.0.0.0, no?

Anyway, I'll send all the info about the BootROM reconstruction service, EnableGop is included in one of the BootROM images.

Sure, PM sent.

I have a Mac pro that's been upgraded from 4,1 to 5,1 - I'm currently running Mojave with open core (Martin Lo 0.7.3.1) I'm wanting to upgrade to Monterey. I got open core 0.9.8. upon checking I see that my boot rom is 9144.0.7.3.1 - do I need a reconstructed Boot Rom? I read that this could help as the 4,1 to 5,1 upgrade was done a while ago. thanks

9144.x.x.x.x and 9999.x.x.x.x are spoofed BootROM release versions, to avoid unwanted firmware upgrades from newer Macs (2019 Mac Pro or iMac Pro are spoofed to run macOS releases after Mojave). Since the spoofed/fake version is being displayed, you should boot native and see the real version.

- do I need a reconstructed Boot Rom? I read that this could help as the 4,1 to 5,1 upgrade was done a while ago. thanks

All cross-flashed early-2009s greatly improve firmware wise with the BootROM reconstruction service, being then equivalent to a mid-2012, especially since the early-2009 incompatible NVRAM volume is repaired and upgraded.
