Optiplex 7080 Locked BIOS

[elijahuff]

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!

You have :

64 ---> 8MB
128 ---> 16MB
256 ---> 32MB
512 ---> 64MB

For example : 25Q128BV... gives you 16 MB bios

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?

Danke!

Use 16pin clamp.

you try Sop16 To Dip8 Adapter 300mil Socket Ic

you try Sop16 To Dip8 Adapter 300mil Socket Ic

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.

Danke!

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

As far as I know, your chip has a voltage of 3v-> 3.6v

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?

Danke!

Be careful, CH341A (black board) has a default voltage of 5v, you must mod it down to 3.3v.

Thanks for the tip mein freund!

[elijahuff]

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!

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.

Danke

Hi, Try

[elijahuff]

Hi, Try

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:

This is a new file, you must try both.

[elijahuff]

Hi! I flashed both files, none of them worked unfortunately.

Danke!

[hoaca388]

This is a new file, you must try both.

You can flash the original file to see if it works.

Did you ever solve your problem? I am in the exact same boat as you with the optiplex 7080
