need help unlocking m6800 bios / nvram variable questions

[fix a pc]

Ok so i came across this random post on how to unlock the bios via FTK 
and use an efi boot file to edit the variables, so i did this and i was able to successfully pull a complete copy of the bios. 
The problem is it was a complete copy of the whole chip and not just the bios, so i used another bat file to pull only the bios  in a bin file.

Now my problem is i cannot open this bin file in AMIBCP.exe to edit the bios because when i try to open it, it says some bios strings exceed max length so setup tab and other stuff isnt shown. 


So since i figured out how to edit the bios variables, i figured i would try to extract the bios some other way besides what i learned from another post.

So i downloaded a few versions of ami flash and tried to use the /O command to save a copy of the bios to a file. 

The problem is , it says it cannot communicate with flash.......

So here is my few questions i have now that maybe someone can help me with 


1. Is there anyway to get a list of ami nvram variables and their meanings so i can look through them to see if i can find some type of other flash lock so that i can use ami flash to extract the bios? or if iam doing something wrong and there is another problem i need to fix with ami flash. 


2. Is there any other programs you guys might know of to extract a dell bios from a dell laptop.


3. Any other ideas or helpful knowledge would be welcomed and appreciated.


GOAL, get a copy of a m6800 bios that i can edit in AMI BCP.

Thank you for your time in reading this it is very much appreciated.
