But I am running 32 bit Vista Business RTM and I have to say it is certainly NOT a warmed over XP.
Mess with the bull get the horns... ;)
// Disable enforcement no signing checks
Bcdedit.exe set nointegritychecks ON
Right, that works on a beta, but from what I've read the final release (RTM) won't load unsigned drivers.. period.

"Additionally, Windows Vista x64 versions require that all drivers be digitally signed by the developer. If you've ever installed a driver in Windows XP, you'll likely be familiar with the unsigned driver dialog, which offers a "Continue Anyway" option when a setup application attempts to load an unsigned driver . In the x64 versions of Windows Vista, this will not be possible. Microsoft says that it is requiring signed drivers so that it can ensure that drivers are of the highest possible quality; poorly-written drivers are, today, still the leading causes of blue screens and other system instability issues."
bcdedit works around that limitation, but will it work on the RTM version as well.. are you using a beta or have you got your hands on the final release (RTM) somehow?
