Windows After the walled garden coming to the desktop operating system world, we're currently witnessing another potential nail in the coffin of the relatively open world of desktop and laptop computing. Microsoft has revealed [.pptx] that as part of its Windows 8 logo program, OEMs must implement UEFI secure boot. This could potentially complicate the installation of other operating systems, like Windows 7, XP, and Linux.

>>>"They have locked bootloaders that don't permit any firmware not signed by Motorola to be installed. Is this approximately what Microsoft is looking to do now?"

Microsoft already does this with win vista/7 kernels. The owner is not free to install independent drivers without buying a one or two year signing key. It seems to be a deliberate attack against OSS in the windows kernel. Just after I was beginning to learn how to write kernel drivers, microsoft banned us from installing our own drivers on our own computers. They've hard-coded private keys.

"Looks like this 'walled garden' concept has nothing to OS security, but rather with vendor security."

Technically, it has alot more to do with bootloader security than OS security, windows will have the same flaws as before.

It prevents unauthorized bootloaders from running. [...]
So, if I may speculate, this is about extending the kernel driver enforcement all the way back to the bootloader so that kernel jailbreaking software like this cannot work:

Maybe it will break those loaders used to bypass windows activation schemes? That alone would be of great benefit for microsoft, specially in the bottom server side of the market...
