After initially attempting to read and verify the files without success using the CH341A programmer ver 134, I was able to successfully read the BIOSes using the "CH341A v 1.31 free" tool, which appears to be a bit simpler but worked. Each BIOS file was read, verified, and saved twice (closing the program and unclipping the reader between each), and then the two saved files were compared to each other and confirmed identical.

I have uploaded the BIOSes here, as numerous attempts to upload them as attachements to this post (directly, with no file extension, as *.jpg) failed due to permission issues. https://drive.google.com/drive/folde...usp=drive_link

Winrar or 7zip

OK, here's all 6 BIOSes

Thank you!

peste asked you to post S/N, full name and model, motherboard model, TYPE,etc. Did you check in the hardware maintenance manual to see if there is a password jumper on the motherboard ?

He did, while ignoring the direct question that I posed and not giving a clear reason - and you did the same. I appreciate that you guys take the time to help people, but I don't feel like my questions are unreasonable. It's also unclear if my original post was actually read - the BIOSes aren't "corrupted", it's simply that 5 of the 6 have a password applied. Being wary of just dumping out the system information on a public website, especially when it seems likely that the windows keys from the BIOSes could be read, isn't unreasonable.

As to the latter part of your comment, do you really think that someone is likely to jump to buying a BIOS programming tool off AliExpress and attempting to get around a BIOS password manually without having tried a CMOS or password jumper?
I have tried the jumper, I have tried tried removing the CMOS battery for extended periods of time, I have tried every viable method that I am aware of for removing the BIOS password, without success.

Read the rules, they apply to everyone. https://www.badcaps.net/forum/troubl...before-posting

I flashed PC0KA977 with the provided BIOS (with the only difference being a zeroing out of 2 rows?), but it is still coming up with a request for the Administrator password to access the full BIOS.

I had a go at flashing the already unlocked BIOS onto PC0KA977, and that worked without a problem. I was able to enter the BIOS without needing a password and has full access, so I'm assuming that the section that was changed wasn't the right password area?

I'm separately having hardware issues with two of the devices now where they aren't powering on at all, but I don't think that's related - at least I hope not.

I would have, had I been aware of them earlier. I wasn't posting a request for a BIOS in my first post - I was requesting information and trying to understand what the risks and options were. As I have said multiple times, I was seeking to be able to resolve the issue myself if possible, but since my post got merged into this thread it seems like the only course available to me is to upload the BIOS files and hope that the cleaned files actually work.

Even the rules themselves aren't helpful - it does no good to mandate that people "Attach files directly to your post instead of linking to external websites" without mentioning that you cannot attach a *.bin file, and should instead provide the bin file in a rar or zip archive.

I'm not trying to be a jerk - I truly appreciate the help and the efforts that have been made, but it's exceedingly frustrating when I am being as clear as I possibly can in my questions, am asking what I believe to be very fundamental information which I have been unable to source via Google, and am essentially being talked over rather than to.
