How to disable driver signing on 64 bit Vista SP1

Question

I am testing a driver for which we haven't got WHQL certification yet. So I need to disable driver signing before I install the driver. Does any one know how to disable this on Vista XP1 64-bit version through command line or some other program? I don't want to do an F8 everytime the system boots to disable driver signing.

I tried the following, as mentioned in a few blog posts:

bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit /set nointegritychecks ON

They might be working on vanilla vista, but they don't seem to have any effect on vista SP1 for disabling driver signing.

Answer 1

I believe F8 is the only way to disable driver signing in Vista 64 SP1. Driver signing is meant to enhance system security, thus there isn't a way to skirt around it easily.
