Intel ICH9R and Vista 64. signed driver issue. can i integrate them ?

Hi all

total newbie to this forum which i have stumbled across in my quest for knowledge.

On one of my machines im running vista 32 on a 4 drive RAID 0 array (Intel ICH9R), the dvd i used to install 32 bit already had the pre-install drivers integrated onto the dvd so i did not even need to do the F6 and insert floppy (to load intel storage drivers). This was great as it was the first time i had come across an install that instantly recognised the raid array without the need to load any drivers from a floppy.

Now my problem.......

I want to install vista 64 bit and dual boot the machine (in readiness for adobe CS4 suite), however when im trying to install this time around the pre-install drivers have not been intregrated onto the dvd and i have to press F6 or choose 'load drivers'. The only issue im having is that vista 64 is rejecting the drivers as being 'Un-signed' and therefore ending the install sequence. Only the drivers are genuine and are digitally signed (or so say ASUS) asus rampage mobo btw

So my question is obvious really.

Can i create a new dvd with the intel matrix drivers already installed on the dvd, or hack the drivers on the floppy to change the signing ?
The drivers i have are from ASUS and are digitally signed, it would seem vista 64 is reading them differently however !

any advice would be greatly appreciated
