Resolved i7-940 and kernel panic

Same symptom as when I tried to do it with 85: reboot, firmware for a second, and crash/restart.
You can backup the full personalised BootROM and flash the 0085.LOCKED.fd file with ROMTool.
You will loose iCloud/Facetime/iMessage and it's better to disconnect from all of them BEFORE doing the the flash or red lights will go on at Apple servers
Just rename .fd to .bin?You can backup the full personalised BootROM and flash the 0085.LOCKED.fd file with ROMTool.

Okay, did it. Serial Number shows as unavailable, and Boot ROM Version: MP51.0085.B00
I'm gonna install the i7 again and see what's what.
[doublepost=1533439655][/doublepost]Interesting results.
With 0085, it boots the i7 just fine, but reports it as a xeon. Geekbench 4 shows the info correctly.

Mac-Pro:~ default$ sysctl -a |grep machdep.cpu.brand_string
machdep.cpu.brand_string: Intel(R) Core(TM) i7 CPU 940 @ 2.93GHz
Mac-Pro:~ default$Save a full SystemProfiler, then do a bigger test:
1) update macOS to 10.13.6, that has the most recent microcode.dat, check if anything changes on the processor identification.
2) upgrade the firmware to 0087 and check if still boots without the microcode on the BootROM and with the most recent microcode on macOS.
I'll have to try that out tomorrow morning, but will do as soon as I'm up.
Yeah, the how's and why's of Apple continue to confound us. I'm sorta glad that it's Apple, and not the i7-940. @ActionableMango was going to do a bunch of work in the CPU compatibility thread, but now it looks like just adding some information about boot rom versions is what's necessary. With 0085, the i7-940 is working, but incorrectly showing in system profiler. I'll get clarification from @tsialex tommorow and well presumably continue. He's probably four hours ahead of me do I'm sure he'd rather sleep than hold my hand through troubleshooting.
- Save a full SystemProfiler, do
Code:
sysctl machdep; /usr/libexec/ucupdate -q - Update macOS to 10.13.6, via software update, without upgrading the firmware. Save a full SystemProfiler again and do:
Code:sysctl machdep;/usr/libexec/ucupdate -q - Upgrade the BootROM to 0087 to check if the Mac Pro still boots without the microcode on the firmware. Maybe it will not boot.
- If you can boot, check what's the macOS microcode version with
Code:
sysctl machdep;/usr/libexec/ucupdate -q
On a Mac Pro 5,1, Apple will only upgrade the BootROM when you run the full installer, not when you update the macOS version with software update/Mac App Store. A lot of Mac Pros are on obsolete BootROM versions, like 0084.

Going back to 2009 with 4,1 firmware the i7 975 showed up as a Xeon in about this Mac, ram should show ecc as disabled. The same happens in firmware 0085 and 0089 with the 990x. You are seeing expected behavior.
Congrats on installing the necessary cpu bits to get it running.

We have at least two questions to answer:Going back to 2009 with 4,1 firmware the i7 975 showed up as a Xeon in about this Mac, ram should show ecc as disabled. The same happens in firmware 0085 and 0089 with the 990x. You are seeing expected behavior.

1) It's the BootROM microcode that provides support to i7 booting on macOS or the microcode.dat?
2) Apple removed Bloomfield support from microcode.dat on the current version?

Yes, just rename the LOCKED.fd to .bin and flash it with ROMTool.

Okay. Once I updated to 0087, I got a kernel panic.

I'm back on the 0085 firmware.
So, with this we have some answers:
1) Bloomfield i7 CPU cores need the microcode on the BootROM to run macOS, unlike Nehalem/Westmere/Gulftown Xeon cores that can boot macOS without any microcode on the BootROM.
2) Apple did update the microcode.dat on 10.13.6 to support 0x106a4 CPUs, from 0x11 to 0x12.

If you want to keep running the i7-940, you could try to add 0x106a4 microcode to 0089, like we did with 0087 when Apple forgot to include the microcodes.
