I Have 2 5090 optiplex's that have the Bios admin locked, both on 8FC8 Bios, i have a ch341a but only with a 8 pin clip, have ordered a 16pin clip, the chip on the motherboard is a Winbond 25R256JVFN, would i need to modify the 16pin clip one i get it, or will it work with no modification? i have the v1.7 of the ch341 with voltage adjustment.

Thanks

Need some help,
Managed to read the 25R256JVFN bios chip, took 2 copies, made the modification of searching for "00 FC AA" and replacing it with "00 FC 00" ( nothing came up on this one ), then the same for "00 FD AA" and replacing it with "00 FD 00" had 2 entries. Erased the chip and wrote the modified bios file to the IC, pc would not boot at all, only orange power light came on and off.
Erased the bios again and wrote the original copy, still would not boot, any ideas?

Both files attached

Any help appreciated, Thanks

You failed because the backup failed.

You failed because the backup failed.

How can i verify the backup is correct before erasing the Bios chip?
I have another identical unit, will pull the backup off that and try and put it on the 1st machine before proceeding.

Dell laptops store the password in EC. However, some generators exist depending on the code suffix.
See: https://beta.bios-pw.org/ .If the website is offline try: https://web.archive.org/web/*/https://bios-pw.org/
Note: All passwords must be entered with a US QWERTY Keyboard,you can use a USB one.
Note: The 6FF1 suffix has a bug,use your service tag with the 1F5A or BF97 suffix instead,Example: 1234ABC-BF97 .
Note: The list of examples does not include some other suffix codes that do work,such as E7A8 .
Note: If the BF97 suffix does not work try it with the E7A8 suffix instead.
Note: There is no publicly available 8FC8 generator available at the moment.
The CTRL-ENTER-ENTER keystroke after the password only applied to laptops with a suffix (xxxxxxx-8FC8 for example), until Dell also required it in some laptops using System Disable 16-Hex algorithm, on which only the Password+ENTER was needed at first and then in some models you needed the CTRL-ENTER-ENTER to properly delete the system passwords, otherwise the password would remain SET upon the automatic system reboot if just doing Password+ENTER until the proper CTRL-ENTER-ENTER keystroke was performed in certain models.
