Hello! Did you get the file? I need too. I have a DUMP of a original one that blinks 5 whites and 2 Amber LED, if you wanna try: http://www.topsys.com.br/bios/3060SFF.bin

@laboratoriotopsys Broken update from 1.2.22 to 1.15, just replaced all static parts with 1.15. ME (very old) and NVRAM untouched.

hello guys is this BIOS unic ? do i need to patch each of my 3 units? or can i write this zip file in any of my unit???

[lfb6]

Yes, it’s unique:

• Theres machine specific information in NVRAM and DVAR block in first EFI volume after NVRAMs
• ME is still initialized for that specific machine

In addition:

• There are 2 bios region version types for these machines, you should use the correct one
  .

Procedure:

1. Dump every machines firmware
2. Empty NVRAM for one firmware
3. Re- initialize ME for one firmware- this ME region might be used for all machines if not booted before
4. Backup the DVAR block for the corresponding machines and transfer it in a specific firmware image for every machine

OR:

1. Repair every firmware individually

…however is there any video that shows the process?

Not that I know of.

@Data-Salvage-F

what programmer should i use for the dumb?

Normally a CH341 would do. Lots of content in the forum.

For re-initializing ME- follow this guide:

[Guide] Clean Dumped Intel Engine (CS)ME/(CS)TXE Regions with Data Initialization

Guide-How To: Clean Dumped Intel Engine (CS)ME/(CS)TXE Regions with Data Initialization Last Updated: 2020-07-22 This guide is relevant to those who need to clean the DATA section of an Engine (CSME, ME, CSTXE, TXE) Region, which is part of a dumped SPI/BIOS image, in order to flash the latter on a different machine of the same OEM model. It is not meant as a guide on how to completely transform a dumped Engine region into a stock Intel-provided one. Although the guide can be used for that some…

thank you for the answer. what about the people online claiming they can unlock it with a password without the dump file? how possible is it? do they have access to DELL or HP server?

@Data-Salvage-F

what about the people online claiming they can unlock it with a password without the dump file?

You didn’t write anything about unlocking or a password, you just asked if the attached image was specific to this machine.

Regarding ‘people claiming’- Ask those people claiming something!
