[SOLVED] Change Serial Number, UUID, Machine Type, and Product Name on Insyde BIOS

[dsdn1]

Same problem after the replacement of the dead original bios chip in lenovo G455. But my board is old (y2010) and no UEFI support, will see how it works. But with full optimism. Thank you so much!

Hello,
Recently I bought a new motherboard and the serial number or type information says "INVALID"
This is the motherboard: B71-80 (NM-A491).
Bios: InsydeH20 rev 5.
Version: 0RCN35WW

Do you know the procedure for modifying these values?

thank you in advance for your help

Hello, I have edited the values using the software. Does someone know how I can change the baseboard name, and OA3 key? As Windows shows the baseboard as INVALID, and the OA3 key as NO DPK.

In that package is lvardos.exe, with /? switch you can read this:
