HP Z420 WINPE 2.1 Issue

Hello All,

 I have a new HP Z420 that when I attempt to deploy an image that it doesn't see the hard drive after intial boot screen. I have tried loading the storage driver from HP with no avail since they don't have a Vista driver. I also tried importing the Texas Instuments controller driver in to the preboot as well and receive "Driver did not match device class filter" since it's written for both x86 and x64.

Any suggestions would be a great help!

Thanks,

Kyle
