I managed to extract my BIOS... I was afraid it was corrupted..

[marek kratochvil]

Thank you for your help, but I need a BIOS file to reprogram my chip because it's dead... Could you please help me? Thank you

[marek kratochvil]

I found a chip next to the BIOS battery... "XMC" QH2568XI... THAT'S THE ONE.

[marek kratochvil]

Okay, thank you for your help! Where is this chip located on a standard circuit board, please?

[peste]

don't pay me..pay on the site...there's a button on the top left...or contact the site administrator..

One question...on PayPal for donations it says "Component Analytics..." Is that you?

post the contents of the bios chip even if it is corrupted..

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

[marek kratochvil]

How do I extract the "for original BIOS" file, please? Yes, I'll pay 10 euros via PayPal...of course.

Thank you very much for your help, but don't torture it anymore, it's really annoying me, I've wasted hours with it now and in other days, I've rewritten the original memory, 2 new ones, with a new one it behaves differently, with the same bin you posted here modified, only the power button and power LED on the front edge light up, but this time orange, not white like usual, I suspect I made a mistake with the hot air station, although I worked carefully, disconnecting the main battery, the bios battery, the power supply....
so I'm giving up until I take it apart, keep it maybe in the near future I'll find an identical one and have spare parts
once again
Thank you

If you press the power button and the front LED lights up amber, then I would suspect that the BIOS chip isn't properly seated on the motherboard.
Watch this video; the same thing happened to him, and he describes having a solder bridge.

The error in the video is at 3:58
You could also upload a picture of your soldering work.
I also use the RT809H programmer myself, so that shouldn't be the problem.


I had to unlock a Dell 5540 notebook myself, and with this model you have to be very careful not to damage adjacent components when de soldering the BIOS IC, as the components are very close to the IC.
But it worked.
Important resistors are placed very close together, as you can see in the picture.
