When I use just Chipset & MassStorage alone it works fine.

In the beginning of the Win7 install, im getting:
ifp63x64.sys cant be found
0xc0000098

The file resides in:
\DPBASE\DriverPacks\DP_LAN_wnt6-x64_1208\x64\Win8\L\Intel\5

I am using WinToolkit140-77 for my slipstreaming
Server 2008 R2 Hyper-V for testing.
