Thanks, I have compressed and attached the dumps of both chips to this reply and I will go back to the original post and edit them in there too.
I appreciate all of your patience and advice.

Edit: unable to attach to original post....

Hi there, Yep, i'm aware of 7zip and WinRar, but my .bin files are in the google drive folder linked in the post... What do you want me to do with 7zip? Compress to a zip and attach? Are you able to help patch my bios? Thank you ever so much!!...

Thanks for the reply! I don't know if this will reply directly, I've never really used forums before. Will 7zip allow me to convert .bin to .ext? Is that what you're saying? If so that'd be great!
Cheers...

Hi all, my first post here. I was recommended this place, I've got a recently acquired x230i tablet running BIOS version 2.51 (GCET91WW). Some sort of supervisor password is set and I cannot access any of the secureboot etc settings. I've dumped the bios (both chips) with a CH341a and verified the dumps. I tried the autopatcher to no avail. Attached are the files, in a drive link as BadCaps wouldn't let me upload .bin's. Any help with this would be fantastic and much appreciated. The laptop boots fine, and posts to bios.
