DMI transferred from your old bios backup:

Thank you very much,
I really didn't know why I couldn't change the information. I was validating your file and if there is DMI information in the sector 0x1000 to 0x2FFF, but your new BIOS file is encrypted on BC base and mine changed the encryption key to 54, FF, etc. I also noticed that it has more information at the beginning. Which method do you use?. Thanks for the help as all the information is in the BIOS. It seems to me that the motherboard was at some point replaced.

😀😉

Upload the file here so we can see what you were able to create and if it was correct or not.

[gliecer]

you have everything you need at post#52..use the HxD program that you can find for free...introduce both bios into it (the original laptop and the one from post#52), copy the DMI interval (from post#52) from the laptop bios to the virgin bios...(copy-paste)...and save...

Hello good morning,

I did indeed follow the steps of publication # 52 (. How to make a macro script) and replace the following fields in the new BIOS.

7. Copy 0x0520000 into Seletion start and 0x05207FF into selection end ,then click on OK
10. Click back to the oldbios.bin tab and make a new selection (step 6) with 0x062D000 and 0x062D03F and follow steps 8 and 9 again

I saved and installed the .bin.bak file on the laptop but it doesn't work. (If it turns on but the DMI information is not)

I don't have a healthy backup BIOS. I only have the backup after being corrupt. maybe the DMI information was lost because the BIOS was corrupted.

There is another way to insert the DMI information into the new BIOS or there is no longer a solution 😥

Thank you for helping me.

Good morning, I'm trying to create the DMI but I can't, I think I'm missing information. Vesko356 hoaca388 could you help me please.

I am attaching the BIOS backup that is working after reviving it 😁 and the damaged BIOS backup before erasing and installing the stable BIOS.
Thanks for the help, I thought I wouldn't be able to use it again.

Re: Hs461 hs561 hs761 nm-d521 rev 2.0 bios plz

thanks, but still not working.
Is maybe the chip broken, if i try to verify the chip then i get every time different memory address

Verify memory...
Verification error on address: 00000296
Execution time: 00:00:00.033
Current programmer: CH341
19:53:11
Verify memory...
Verification error on address: 000000AE
Execution time: 00:00:00.031

Hi guys, I did it
i had some small disconnects all the time on my usb ch341 i didn't realize and that was the reason why the memory was corrupted.
I tried with another laptop and it works.
and sorry, I know this post is not supposed to go here. But just wanted to thank you all for your great help.
