Bios Mods -The Best BIOS Update and Modification Source

Had a motherboard changed in an Acer laptop. The same MB is used for several models. The DMI System Information reports the wrong Model Number. How can I change this information? Thanks

Bios Links? Model numbers? Links to info? name of replacement motherboard? help?

The correct model is Acer Aspire 5570. The motherboard must have come from a Acer Aspire 3680. The MB is known as a ZR1. The bios for both are at the Acer support site. Its the same bios. The wrong model number is reported in the System Information of the DMI.

not sure if this is going to work but ive downloaded the latest bios , opened it with Phoenix bios editor and edited the default DMI string for Model to read Acer Aspire 5570.

Flashed the bios, but still reports wrong model number.

oh sorry , thought it might not be as easy as that - Id flash back to the original if i were you.

Download this DMI Editor , should work as it mentions Acer in some documentation

Now create a bootable DOS USB/CD/DVD (there is a guide on this site) and copy the files that you downloaded above onto the bootable disk

Restart your computer and when you get to the DOS prompt type the following command:-

dmi /wp Aspire 5570

Press enter, reboot and remove bootable USB/CD/DVD

Check bios , model number should be changed - this is how Acer technicians program the DMI and UUID info to start with

Let me know how you get on
