The following was posted in the ecs forum over at ocworkbench. Enjoy.

BIOSLOCK is an identifier in the BIOS that OEMs use to "tie" their software to their hardware.
For example: you buy a Dell computer and you get the cd for "system restore". How does Dell make sure you don't use that disk to install their OS and software onto another computer? Simple, they make the software check the BIOSLOCK ID before installing. If the ID matches, it installs, if it doesn't match that means you're using the software in a different computer.

Another example: The pre-installed versions of Windows XP that Dell and others are selling don't require authentication. Why? Because Windows install uses the BIOSLOCK to detect if it's the same motherboard that Dell sold you, if it's not it doesn't install. This allows OEMs to sell you a computer that no matter how many changes you make to it, as long as it's the Dell motherboard, it will not require activation.

Here are the changes:

The previous BIOS versions had only one BIOSLOCK ID:


Version 011016 includes two BIOSLOCK IDs:



I hope this explanation helped. As of right now, there's no reason to upgrade to the new BIOS. We'll have to wait and find out if ECS added other "undocumented" fixes to new BIOS.
