Add video drivers to WinPe in SMP 7.6

Hello,

I have upgraded to SMP 7.6, and have created a Preboot Configuration image using WinPe 3.1.  Adding drivers via the SMP console works great for NIC and Storage hardware, but does not work when adding Display drivers.  Every time I try it tells me that no drivers were added.  I have the correct Windows 7 video drivers for the hardware models in my environment.  I realize it's not super important since the machine is going to be in WinPe very briefly, but being able to properly see what is happening helps when troubleshooting why WinPe is not connecting properly.

Is there a way to add these drivers?

Thanks

Alex
