I’ve bought two ex-enterprise Asus Z370-A mainboards where I need to remove the Win 10 OEM license. I would like to get this done by using a CH341a programmer but I am already struggling to find the BIOS chip on the mainboard.
According to someone from linustechtips forum it should be the red circled chip on the picture:
I’am not fully convinced that this is the BIOS chip. In my case this would be Winbond 25X05CLNIG
I found a 25Q128A chip that is close to a SPI header?!
What do you think? How do I distinguish if 1.8V or 3.3V is needed? Is there maybe an easier way to remove a WIN license from BIOS?
Thanks for your help. I was able to dump the bios and remove the Win10 license. Unfortunately this didnt solve my problem. Do you know how a system/pc is linked to a specific MS account? I’ve bought a used workstation from a company sale, installed my SSD and ran WIN10 setup. When the network cable is plugged in during installation I get the following message “Welcome to X-Y-Z company - please fill in your X-Y-Z company email address”. A specific user account [email protected] is prefilled → next screen asks for a password for this account. How does the unit recognize it has to connect to the company? Is that a specific UID in BIOS that makes it connect to the company’s account? Would a fresh stock-bios fix this behaviour? I’ve already spoke to the company’s IT department but they didn’t have time to help.
Yes its HW UID linked to a MS licence, bios SLIC/OEMCERT etc… so u didnt programmed a regular Z370-A bios from Asus…i thougth that this was ur goal… Search on forums in mydigitallife.net
