Greetings i am in the process of reverse engineering the bios logic for the 8FC8 suffix so far I have found most of the bios functions related to the suffix from a bios dump and I have verified inputs and outputs to test with plus the chartable for the 8FC8 suffix.

how good! -
I just thought about it, and decided to give it a good 'ol google search... and comes along your post on the 3rd result lol
Have you had any progress? I mean it shouldn't be impossible or if I could take a guess at least, something that has been done before.
I found there's people on the fleabay selling you a master password for 75 dollars, and has over 180 combined sales so far... Also in the BIOS of all of these newer models the "Master Password Lockout" option still exists. Which means they have a master password.
Just my 2 cents.Comment

RE still in the works, but in the meantime, the next best thing is the updated Python script
https://github.com/chromebreakerdev/DellBIOSTools.git based on REX 8FC8. You can download just the raw Python file "dell_bios_tools.pyw" if you prefer. It has the 8FC8 patcher tool and old Dell master password generator combined.Comment

I am aware of REX's patch, it works wonderfully; but I meant reverse engineer the master password... not modify the contents of the BIOS flash chip.Originally posted by LBTT1121 View PostComment

Yes, the master password algorithm is present on "8FC8" devices, just like in older BIOS versions.Originally posted by kuiri View PostComment
