You have failed the backup and the bios chip shows it as 16MB of data.

Re: Bios Dell Optiplex 3050 Micro

Hello

I need help !

I have a Dell 3050 Micro that won't start... It displays 2 led flashes (orange) then 5 led flashes (white)

It's probably a corrupted BIOS problem.

Can you help me find the right file to reprogram my Bios chip?
The EZP2019 programmer does not come to anything and does not recognize Winbond 25Q128CSIG chip - It tells me that it is an Eeprom93!

When I set manually on the Winbond 25Q128 and I start the process, the writing starts then an error appears after checking the writing. The Bios chip does not keep any data and remains empty!

I have the impression that this programmer is not very reliable! Do you have a reliable programmer to advise me?

Serial Number: 2B551M2 / Express Service Code: 5027326058

Thank you in advance for your contribution !

You can try the 2 files in #4 but must read your bios chip first to make a backup of the original bios you can try with CH341A programmer, this is the cheapest one, pay attention to the voltage of this type (the black board has a default voltage of 5vol) in addition you can use the Rasberry Pi with the Flashrom tool.

Re: Bios Dell Optiplex 3050 Micro

Hello;

Thanks for your quick response and advice...

I have already tried the 2 files in #4 - But nothing works - With EZP2019 + croco clip (even at low speed) it ends in failure (flash check error address 0h)

In reading, the original chip seems empty! So difficult to recover an .OLD file

I will wait for a possible other solution while waiting to receive a new programmer to try again!

Re: Bios Dell Optiplex 3050 Micro

Correction !

Back to my original post!

The BIOS chip is not a WINBOND - It is actually a GigaDevice 25B128CSIG

After buying the CH341A programmer - I managed to rewrite the BIOS - My various attempts brought me different LED diagnostic codes, but the PC does not start...

I managed to recover the Bios 3050.old and I reinstalled it as at the beginning - I am now waiting for your help...

Can you provide to us your original bios? and also write your Service Tag.

Re: Bios Dell Optiplex 3050 Micro

A big THANK YOU to you for the 2 files that you sent to me...

I tested these 2 files; unfortunately, after installation, the PC displays a new error (2 orange leds + 3 orange leds then repetition)

Ditto for the 2nd file!

Thank you anyway for the time you spent and your quick response!

Good Afternoon All. Please accept my apologies as I am a newbie and don't quite fully understand BIOS programming. I have a Dell Micro 3050 (old BIOS attached), service tag 43LXXK2 with a 2-1 amber error code. Hopefully it can be rescued with this. I'm not sure how to edit this bios as Dell PFS Extractor produces 2 separate folders, each containing a 9MB bin file. Thank you for your support.
