I agree, in every case it is a thing to look closer.
That is the intension to check it and write a note if it is in unusual order.

my macpro 4,1-> 5,1 also has this same message:
Fsys: 0 override-version, 1 ssn, 2 hwc, 3 son, 4 overrides, 5 EOF (unusual)
I bought this macpro directly from Apple as a refurbished unit back in 2009. It has never booted windows or anything other than a Mac OS or been flashed other than Apple firmware updates and the 5,1 update. It is running monterey using Martin's opencore package. It has no problem booting or running apple stuff. I wonder if this "unusual order" has to do with it being a refurbished device from Apple.
I just found your romdump tool looking to put in the EnableGop functionality.
Do you think it is save to proceed with the EnableGop without fixing this order thing?

As it is a 4.1 to 5.1 crossflash (I assume, if it's a reconstructed real 5,1 firmware it writes bootblock of 144.0.0.0.0), it is recommended to do a reconstruction.
Not only for that mixed order in Fsys. That mixed order does no harm at all, but if one part is wrong I would not be 100% sure, that there are no more glitches.
Plus, as said, such a crossflash is not the best way to go for modern OS, heavy use of NVRAM running OpenCore or multiple OS.
You don't give a single word about what you want to do, or what it has to do with the Dumper project or the NVRAM health state.
For dumping with the Dumper: Kext Signing is disabled, so dumping (and checking) the firmware should work.
I want to install windows on my mac pro and was checking the nvram.
And then i saw this message and I was woried something is wrong? Should I be or not?
The sentence that something is "likely to break in the future" is not good? So I thought I needed to change some settings?

I guess, you read the hint about that Netkas crossflash 4.1->5.1 - what sometime tends to break in OpenCore / multiboot configurations with heavy use of NVRAM, when some other things come in play.
The solution for this is not to change some sip settings, the solution is to get a prestine, rebuilt firmware. You can read several posts about this in this forum. Also you have seen the contact possibility...

Thank you for the info @Macschrauber
I have done some reading on this subject and I now understand I currently have a crossflash firmware (4.1 -> 5.1), which works, but could fail in the future.
Best way would be to rebuild the firmware. I did a rom dump, but only after I installed OCLP already. Probably I should have done it before, or this does not matter?

For a rebuild it is important to have the IDs, this works on an OCLP OS.
If one wants a clean as possible romfile of the particular Mac Pro, it is the best to make a deep nvram reset and boot into a supported Os without OpenCore. I prefer Mavericks in this case, as I dont need to lower sip settings to dump the rom.

github.com
- Added recognition for Matt Card.
- Added recognition for more errors found by UEFIExtract.
- Implemented dynamic $IBIOSI$ scan to retrieve BIOS versions of "unknown" machines' firmware and unnamed .fd files.
- Revisited OpenCore LauncherOption: Full presentation.
- Fixed: ASCII values in csr-active-config were not interpreted correctly.
- Fixed: Usernames with special characters, such as spaces, no longer cause privilege errors.
Extra Tools (ESP tools, Repair preboot, etc.):
- Enlarged dialog buttons for wider dialogs.
- Improved recognition of dark and light mode for rendering icons of ESPs and System volumes.
- Revisited most of the tools, more robust recognition of OS' and bootloader variants.
- Revisited Bless OpenCore ESP tool.
- Check ESP for MS certificates: added a setup option to live in the login items to scan for Windows ESPs. Also deactivates them by request or automatically.
Optionally checks NVRAM for certificates when csr values are set as needed.
new tool: Macschrauber's System Version Scanner
- Scans for MacOs and Windows versions
- Presents sealed status ( yes / broken ) for MacOS
- Presents UEFI / Bios variant for Windows

new version of the Dumper 1-9-2024
Dumper:
- Various fixes for running the Dumper as a non admin user.- Added iMac 12,1 dumping via Eficheck.
- Adds MacOs version and CPU configuration to the analyse window and log file.
- Added detailed boot block info, with version and release date.
- Detect more empty .fd firmware files for MP41 and MP51.
- Added scanning dump files file system wide via the cli tool.
- Read and decode NVRAM variables directly from NVRAM via the cli tool.

Sequoia is also promising (it's before attaching root patches):
The Dumper update 19-10-2024
The Dumper:
-> Detects if running on a T2 or Silicon Mac and removes the button accordingly.
-> Added a dialog for missing LBSN/BD sector.
-> Decodes board-id to Mac model in log file.
-> tells the user if the assigned FireWire address does not match the firmware MAC address.
This may indicate that firmware from another machine was flashed on an MP41 or MP51.
test_nvram:
-> Dumping IM121 is forced to use eficheck (available from High Sierra to Ventura) due to a crash when loading DirectHW.kext.
-> "FW MAC matches not with LBSN" or "FW MAC matches with LBSN" line, when the Mac has Firewire and LBSN sector has a firmware MAC address.
-> A catch when Eficheck is not available (before 10.13, after 13).
-> A catch for an empty EFI Version string.
-> CRC32 check for the main firmware volumes for MP41 and MP51 firmwares.
ESP Tools:
-> Detect amdvbflash ESP.
unmount all ESPs, Mount ESP from list, Mount ESP from list and show bootloader:
-> Unmounting has an option to handle busy status of ESPs.
copy ESP:
-> Sets script into a loop, to work on more than one ESP in a row.
Macschrauber's System Version Scanner:
-> more sealed status report.
-> more progress bar steps for multiple MacOS on one machine.
Select Wi-Fi from found networks and Select Wi-Fi from preferred networks:
-> Message and workaround if Airport Utility cli tool is not working anymore on OS since Ventura.
Boot-Args:
-> edit boot-args got into a loop, so editing more options is more comfortable.
Preboot Fixer:
-> mount ESP needs admin privileges if user is not in admin group, fixed when using stored admin / password data.

Update from 18-1-2025
The Dumper:
-> confirming twice if the user wants to flash a MP41 firmware on a MP41 with upgraded processor.-> log firmware MAC address.
-> log blessed OS, if not via OpenCore.
-> report missing Fsys stream.
-> recognise Apple M CPUs, ch341a_spi reading and writing for M CPUs. Needs manual lib installation.
Is damaged fix:
-> added suggestions and adaptions to work in Sequoia.test_nvram:
-> fixed MP51.88Z.0085.B00 was detected as MP51.88Z.0087.B00.-> compare Firewire MAC address just for fw0, for machines that have multiple Firewire interfaces.
-> '-vars 4D1ede05-38c7-4a6a-9cc6-4bcca8b38c14' for example, scans this GUID, only.
-> added flashing to test_nvram, you should check the firmware file, before you flash. MP41 and MP51 units are tested, so far.
Installer for CLI tools:
-> present test_nvram versions from Dumper app and installed version.ESP Tools:
-> fixes for Silicon Macs, as they have no ESP on the boot disk.-> fixes for ESPs on single partition disks.
-> Copy ESP does unmount all mounted ESPs again.
-> fixed: Memtest86 comes sometimes in ubuntu folder, so not detected.
Check ESPs for MS bootloaders:
-> fixed glitch: it does not deactivate Windows ESPs in 5 seconds dialog mode.-> fixed glitch: the variable os is not defined, when running in Yosemite and kext-dev-mode=1 is missing.
Preboot Fixer:
-> Detect Apple M CPUs, there is no preboot / boot.efi.Wifi-Scripts:
-> Select Wi-Fi from found networks displays current wifi network.AVX2:
-> new Tool to scan for AVX / AVX2 codes in binaries. NeedsCommand Line Toolsadded icons for the tools, made by Chatgpt.
