Yeah all looked at, but fixed it eventually by again writing the same BIOS file to the EEPROM. Now it works like a charm again. So this item can be closed and marked as “Solved”.

So you screwed around with the Bios before? Might be worth mentioning in your initial post.

Hello Bernd!

Can you tell me how did you rewrite the eeprom if you can’t see the screen ? … I did a mistake and I flashed the wron verzion of BIOS 🙁 I have the bakcup of the original one … But I don’t know how to reflash it 🙁

[Bernd]

I was able to boot the system and have a bootup screen. I could go to the EFI shell and do the bios flash from the command line as described by one of the posts on this forum.

If you don’t have a EFI shell, then you need to program the bios via an USB EEPROM programmer and a clip. The old fashioned way.

Thank you Bernd !
I’ll try that way, I just have to buy all the stuff 🙂
Can you suggest me what to buy
I can you ser ROM file I created as backup of the BIOS, right ?

[Bernd]

Well, I never did that so I don’t have a clue what you need to buy nor know what to do to get it working again. Sorry

Ok, I studied a bit, and seams that the BIOS Chip is a 1.8V device, so I’ll need an “adapter” for the programmer … I’ll see
