What’s the best way on dumping bios’s on intel AMI systems?

I have a BMAXPLUS B1 mini nuc
One I want to dump the bios either via windows or in Linux.

Two since it’s AMI would the option /O work as I don’t have the /GO to save the full image be enough to dump most if not the whole rom?

Or should I use FWPT for this machine seemed to dump the bios without errors but the problem is even though I did -bios -d etc I only found the rom size was 7259mb or something like that vs the AMI dump with /o gave me a 8192mb as I looked up the winbond chip and found it was 8192mb so far that I can tell. My main question though is what is more complete the FWPT dump or the AMI. Also is the AMI dump just filling in information as like blank partitions to just fill the required flash sized reported, or is it dumping like the intel me and other regions that are required to have a fully working rom being done right?

I know on this intel mini nuc that bios flash protection is disabled so hopefully the os can do a full dump. If AMI or FWPT isn’t giving me the full dump what tool should I use in windows or Linux. Could flash rom on Linux give me all the regions of the bios rom dumped without the use of a bios programmer?

Wait technically AMI gave me header errors and another one I cannot remember but the size and rom id and such had errors that I can think of. Both dumps gave me these two errors except the FWPT didn’t ensure of the rom layout while the Ami seemed to be okay and at least gave me a reading for it. I will say I tested so far that the Ami dump worked as I flashed the Main Bios, NCB, and NVRAM. Problem when I run the Ami v tools I cannot flash the Boot block as I don’t have an option to do so or the embedded controller. Not sure if Bmax gave a limitation on what the AMI tools can read from the bios because before flash I didn’t even have the option to do so. Well it’s getting late for me as I’m central standard time so I will be back tomorrow to answer any questions about this question I have. Also good news at least the AMI dump I managed to flash what I could, and it’s posting and working but don’t seem to unless I’m wrong have the other regions accessible or just locked out of or maybe it’s all in the bios part. One issue after flashing all of those that I could for the rom partitions I cannot access the boot options via F2 but the main bios is accessible and options work and I can boot into other OS”s via setup and the settings in setup save and work fine except Boot options via F2 is broken which is my fault it not a big deal I think as I can still enter setup and all the options including boot management work from that part of it. Later around CST time so 8 or 10am I will be available for a bit to answer anything. So far it posts like it did except I sort of broke a feature, but not too mad as this pc was 85$ on sale on Amazon and still works.

Hopefully this form post is understandable as I’m very tired and typed a whole paragraph on my pixel tablet in bed before I sleep.

Okay so im defiantly glad I didn't try to flash the FWPT dump, I tried to open it in AMI BCP and file isn't openable :(
The 8192mb dump thats from AMI V tools seems to be readable.
Here's a screenshot of the bios dumps compared using AMI.
They're in the main post now
