How is that possible?
Oh, well, that was a typo anyway.
I don't see a reason why this wouldn't work.

Re: Panasonic Toughbook CF-C2 please remove bios password!
I have news.
With your (both) .bin i'm able to enter bios and change everything, except the supervisor password.
Seems like the password is stored to another location of bios too.Last edited by Andreasbest; 01-27-2021, 06:04 AM.

Re: Panasonic Toughbook CF-C2 please remove bios password!
I have more news, my bios seems like it's modified to restore several settings when "load defaults" and also a Panasonic supervisor password that set as default.
Here is the link with info regarding bios ending with M like mine (M10) https://customrugged.com/m-bios-panasonic-toughbook/
So there is indeed a bios password elsewhere inside dump stored by Panasonic, probably in "default settings" section of bios.Last edited by Andreasbest; 01-27-2021, 06:32 AM.

Re: Panasonic Toughbook CF-C2 please remove bios password!
Thank you SMDFlea but i just bought a clean bios dump from a site, unfortunately none gives it for free.
Anyway, i managed to enter bios, supervisor passwords are clear and everything can be modified BUT
if i do "load defaults" the password returns and i must reflash the bios.
So these "defaults" are stored in bios chip itself OR somewhere else?
I suspect that this thread will become a guide for anyone that buys M bios Toughbooks.

you can share us your file which works in mp
here is the file that worked too.
Please compare it to found out where is the supervisor password stored in my backup.
Although i have serious reasons to believe that is stored elsewhere than the bios chip since it's a M model like i said before.Last edited by Andreasbest; 01-27-2021, 09:20 AM.

Originally posted by SMDFlea View PostDid you try setting a new password rather than setting bios defaults. Theres another password for the Optional Kit Configuration: toughkit
With the bios i bought i can set a supervisor pw that works, unless i do "load defaults" then changes back to the unknown supervisor pw.
"toughkit" doesn't work either.
Panasonic did terrific job in this i have to admit.Last edited by Andreasbest; 01-27-2021, 09:46 AM.

Re: Panasonic Toughbook CF-C2 please remove bios password!
Are you tring without the HDD attached. Post a picture of the pass screen.I doubt its stored in the EC ,what is the EC chip ?
Edit: did you remove the CMOS battery and clear it by shorting the battery pins for 20 seconds or so ?

.
The screen is the usual Toughbook password screen.
Yes CMOS battery is detached from the beginning, no power on MB except the PSU when i plug it.
I also tried 20secs short circuit.
Well i'm almost convinced is stored into EC.
