I don't know, but this is parsed by the OS and can be used to configure settings automatically. Probably only makes difference if you have rc.server/macOS Server installed.

I just picked up a gorgeous 2012 5,1 Server. I'm waiting for my new X5675s before I get it up and running; do you have an example of this model for your bootROM collection? I'm gonna have to have you magic up a 140.0.0.0.0 anyway...

I have one but it's corrupted, so I can't trust it.

Send me the dump in the same PM thread of your previous one, I'll check it. Thx, Daniel.

Just put in my tracking number into a Parcel app...my CPUs are being delivered TODAY. So I should have that bootROM headed your way by tomorrow.

Hi tsialex,

Thank you for all your contributions to the Mac community! Perhaps my ROMs be of use.
I have multiple EFI-booting installs (Mac, Windows, Linux) and CSM-booting installs (Windows, Linux).

I got the machines used a few years back and both had FW 84 and upgraded processors from stock (W3565, W3670). One is a 4,1 -> 5,1 upgrade, the other a 5,1. Both are now running x5680s.

I upgraded to 89 to run High Sierra / APFS and had saved the bins from each upgrade.
The 2010 would not boot EFI Windows 10 after the 89 update.
I did not attempt to boot EFI Windows 10 on the 2009 after the 2010 showed issues.

EFI Linux Mint 18.2 showed a screen before starting GRUB along the lines of "searching for APFS volumes" which was new with the 89 firmware on the 2010. I will try to get a screenshot of the exact message when it appears again and also see if it also occurs on the 2009.

I have been cautious with my Mac Pro's after seeing your findings and having to reinstall Windows. I am holding off on 138/140 & Mohave until I receive an MVC metal -capable graphics card and am confident my machines not having any corruptions.

Here are the results of the binwalk:

Whenever it failed to boot EFI Windows?

I was not tracking this issue before, just what causing the bricks and the descriptor. Talking with @h9826790 brought the Windows question to my attention.



I think that @UCDHIUS had 2 SecureBoot certificates and just one Windows UEFI install, he can confirm this. Maybe this again could be caused by crashes, he was overclocking his Mac Pro.

Yup, its just one Windows 10 install.

Have you tried: <resetting parameter RAM>

Whenever it failed to boot EFI Windows?

Yes. PRAM reset had no effect.

I then successfully updated to 0140 BootROM reconstructed by tsialex.
No change for Windows. It freezes right after choosing the drive in the boot screen. (Cursor lockup, etc.)

A similar EFI Windows setup (10.0.16299.431) on the 2009 booted fine with 0089 and tsialex's 0140 BootROM.

I have seen this when it tries to boot EFI as CSM or maybe vice versa.
I saw the lockup on both machines right after boot screen when booting from Windows Installer USB if the drive is not created "just right." Posts in other forums implied Windows not liking the new microcodes. Others showed the latest Windows update causing issues. It could be many things. I also replaced the SATA cables running to the ODD drive cage when this first occurred so the old cables may have corrupted the install.

I will reinstall Windows later and see what shows up.

Attached is the screen from Linux EFI booting after BootROM 0089.
This is probably not new info, but I hadn't come across something like it on these forums.

I have seen this when it tries to boot EFI as CSM or maybe vice versa.
I saw the lockup on both machines right after boot screen when booting from Windows Installer USB if the drive is not created "just right." Posts in other forums implied Windows not liking the new microcodes. Others showed the latest Windows update causing issues. It could be many things. I also replaced the SATA cables running to the ODD drive cage when this first occurred so the old cables may have corrupted the install.

I will reinstall Windows later and see what shows up.

Attached is the screen from Linux EFI booting after BootROM 0089.
This is probably not new info, but I hadn't come across something like it on these forums.

Did you try 3 times normally Windows offers repair solutions where you can choose safe mode. Sometimes I have video driver issue with same symptoms after the 3rd attempt I go to safe mode and reinstall the drivers. Just force shutdown and restart 3 times and see if it offers Windows repair. What revision is Windows do you know by any chance?

Thanks for the thread all. I now have a samsung 970 evo in the bottom slot of my mac pro that boots mojave. However, on the blackmagic disk speed (version 3.2), it's just reporting a speed of 300 - 500 MB/s. This seems too slow. Any reason why? Graphic card is RX580. Disk is partitioned 500Gb APFS case-sensitive and 500Gb MSDOS-FAT
Don't get me wrong, but this is unrelated to the BootROM thread, let's get on topic here.

Please ask your question in the correct thread: Blade SSDs - NVMe & AHCI

there was a 0082? guessing that was some sort of internal build?

as the first public BR update after B03 was 0083 in one of the High Sierra DPs.

It’s a beta one, probably internal or limited release. This one was listed sometime ago into one of the efiflashers, like MP51.007F.B0[0,2].

I saw a single tray last week on eBay for less than $80 with shipping. I think that is a good buy to test CPUs, if you have a friend nearby that wants to do the same upgrade, buy a single tray and test all CPUs before de-lidding.

Hi, De-lidded my X5680's, went very well. With a paint stripper.
I want to use the CPU's one by one in socket A. How do I do that? Can I remove CPU "B" and its memory and leave the cooling tower off?

I know that I can use my 2009 cMP with 1 cpu, but my question is: what have I to remove to use only CPU A?
Do I remove the memory for the B CPU, can I leave the heatsink for CPU B off?
Obviously I have to remove CPU B, but what to do with the heatsink? Just leave it off?
Memory and heatsink. Fans will go full blast. Just use it for checking the processor.

Do not put anything on the socket if no CPU at there, you don’t want anything accidentally touch the pins and bend them.
