Re: Dell Latitude 3550 Bios Dump Plz
hello
I have 2 problems
After programming this file, when i take off the cmos battery,the system should restart several times automatically but it doesn't. it starts once without display and turns off then doesn't start automatically again . after that i should start the system manually in this condition the system runs normally and there is display. additionally when the system is off for some time, the power button doesn't work so i should take off the cmos battery again and run this procedure once more.

Hello,
I have a Dell Latitude 3550 that is locked with a BIOS admin password.
I need to remove the Bios password so I can enable the built-in Wi-Fi card and make BIOS changes.- Model: Dell Latitude 3550
- Service Tag: 1R5J384
- Hash Type: 8FC8
- Current BIOS password status: set and unknown
Thank you very much for your assistance!Comment

There is no publicly available 8FC8 generator at the moment. You would need to backup the contents of the bios chip and then it can be modified. https://www.badcaps.net/forum/troubl...rces-and-toolsComment

Hello everyone,
Iโm hoping someone can help me locate a verified original BIOS dump for my Acer laptop.
This is NOT a BIOS password removal request.
Iโm looking for an original 32MB SPI BIOS dump to use as a reference in case my BIOS firmware is corrupted. My plan is to first dump and back up my own BIOS as soon as my programmer arrives. I am not planning to blindly flash someone elseโs BIOS.
Laptop Information- Model: Acer Predator Triton 16 PT16-51-99GL
- Motherboard: DA0ZQDMB8AE Rev. E
- Main SPI flash: Winbond W25Q256JVEN (32MB)

Hi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.
so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, ๐ ๐ ๐ ... -
Hi everyone,
I bought a used Dell OptiPlex 3090 Micro with a BIOS administrator password that I cannot remove. Dell support refuses to help without the original proof of purchase, and the seller is unreachable.
I would like to try flashing the BIOS chip with a CH341A programmer, but I need a clean SPI BIOS dump for this exact model.
Here are my machine details:
Service Tag: 50P1BB3
Express Service Code: 10925963391
Form factor: Micro
I can share my current BIOS dump (read with CH341A) for comparison if needed....
