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

Great post, one question:

I have a Ideapad 3 14ALC6 with motherboard Hs461 hs561 hs761 nm-d521 rev 2.0, and i will CH341a programmer, but chipset GD25LR128DSIG not found in data list (ASProgrammer or Neoprogrammer). Is there a way for me to add the chip for programmer with CH341a 1.8v adapter?

The closest chip I could find listed was the GD25LQ128C 1.8v

try a similar chip from the data list and see if you can read the bios chip, then post the content here..

Try the BIOS from Post #31.If it works fine we can transfer your DMI.

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.

Thanks for the help, I thought I wouldn't be able to use it again.

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.
