Hello. Thanks for the file, but I don't think it worked.
After flashing the chip, when I power on the machine the LED blinks orange 3 times, then white 4 times.
No image is displayed.
Are you sure the changes you made to the file are correct? Because I only see two small differences between the original and the file you sent me.
Edit: Also I found ths:
[ATTACH=JSON]{"alt":"Click image for larger version Name:\timage.png Views:\t0 Size:\t25.6 KB ID:\t3172728","data-align":"none","data-attachmentid":"3172728","data-size":"full","title":"image.png"}[/ATTACH]... -
Can someone unlock this dump for me? I think I got the file correctly from the chip.
Dell Optiplex 7080
Edit: Just added a newer file which seems more complete.

Does anyone know what do I need to do to set this CH341A to work under 3.3V?
I think it has to do with the jumpers, but I can't figure it out anywhere.
Danke in advance!Leave a comment:

Great! So tomorrow I'll find a 3.3v CH341A EPROM to start testing!
If I upload my locked BIOS dump here, will you help me by changing it to be unlocked so I can flash it to the chip?

Will I need a 1.8v adapter to extract data from this chip? Does anyone know?

I cannot use this because the chip is welded to the mother board. Is there a clamp kit that I could use?
I apologize, I'm still a rookie, I'm trying to understand how these things works.

Hey! Thanks for your reply. This is the only thing that looks like a BIOS chip to me.
But the problem is, it has 16 pins and not 8... What tool should I use/purchase to extract the chip data?
Can you guide me a little?

Optiplex 7080 Locked BIOS
Hello my friends!
I have a locked Optiplex 7080 BIOS that I would like to unlock.
The problem is, I cannot find the BIOS/CMOS chip on my motherboard. I'm having a hard time finding it probably because of my age.
Can someone help me out by explaining where is the BIOS/CMOS chip located in my Optiplex 7080?
I tried to find it just by looking in the board but I couldn't find it.
The computer is a Dell Optiplex 7080 and I believe the motherboard model is E93839.
Danke! -
Hello my friends, my name is Elija, I'm german and 58 years old.
I started learning computing to make my time more useful.
Now I'm studying motherboards and how BIOS and CMOS works on it. I'm pretty sure I'm gonna learn a lot in here.
Danke!Leave a comment:
