Dell t420 Install 2008 R2

Trying to install 2008 r2 on Dell T420 and it would not find the drivers for the Dell PERC H710 Controller.

I downloaded the Drivers for it: Microsoft Windows 2008 R2 SP1 64 Bit Driver for Dell PERC H310/H710/H710P/H810/SPERC8 on and it was an EXE which you cant install on win7 or 8 or a 2008 r2 vm

Call support and found that you have to take the SAS-RAID_Driver_XYPYC_WN64_6.803.21.00_A07.exe and change the exe to .zip and get the Payload folder and put it on a thumb drive and load the drivers in the installation prompt.
