Windows 8 - unsigned drivers?

To run this technology preview, you must uninstall previous versions of workstation before installing this software.  Please note that the drivers included in this survey have NOT been signed and invites you accordingly during the installation.

I see public forecast says it uses drivers unsigned - before you go ahead and remove my installation could present someone please confirm that it is possible to install on Windows 8 64 preview with drivers unsigned despite a uefii boot process.

I was under the impression that it is just not possible.

The drivers are signed, they have simply not WHQL certification. Microsoft requires that the drivers are signed with a type of digital signature to load on 64 bit versions of Windows Vista and newer - if the driver has this signature, it will load, but Windows will display a prompt in the normal installation, unless the driver has passed the WHQL certification, in which case it gets signature from Microsoft that allows it to take in silent mode.

Boot BIOS or UEFI does not affect this.
