Re: Dell Latitude 5500 Bios password

Hello!
Please remove the BIOS password.
As far as I understand, only the 8 MB chip needs to be edited.

3.4. Dell

Dell laptops store the password in EC. However, some generators exist depending on the code suffix.
See: https://beta.bios-pw.org/ .
Note: The 6FF1 suffix has a bug,use your service tag with the BF97 suffix instead,Example: 1234ABC-BF97
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.

1. How to dump and flash
1.1. BIOS
BIOS can be updated from software using the manufacturer's tool. It can also often be dumped from software (although not really reliable).
However, if you need to re-flash the BIOS because the computer does not boot and BIOS recovery procedure does not work, you need an external programmer.
Likewise, if you want to modify the BIOS to remove a password, it must be done with an external programmer.

When flashing a BIOS always make a backup first. Take 2 or 3 different dumps and make sure they are identical.
On Windows, you can use the command "fc /b" to check if two dumps are identical.
Make sure that the dumps looks good, i.e. not filled with 0x00 or 0xFF. After compression, if the file has a size of only a few kilobytes, the EEPROM was most likely not read properly.
