Driver/CUDA will not install - Telsa K80 - PowerEdge C4130

Hello, I have a Dell PowerEdge server with 4x Tesla K80’s installed running Red Hat Enterprise Linux 7.2. When I try and install the Nvidia driver for these cards I get:

WARNING: You do not appear to have an NVIDIA GPU supported by the 352.99
NVIDIA Linux graphics driver installed in this system. For further
details, please see the appendix SUPPORTED NVIDIA GRAPHICS CHIPS in
the README available on the Linux driver download page at

These cards are not my main display card, they are for GPU computation only. The slots they are plugged into (they came installed from the factory) are enabled in the BIOS.

If I skip past this error, the install continues and then I get this error:

ERROR: Unable to load the kernel module ‘nvidia.ko’. This happens most
frequently when this kernel module was built against the wrong or
improperly configured kernel sources, with a version of gcc that
differs from the one used to build the target kernel, or if a driver
such as rivafb, nvidiafb, or nouveau is present and prevents the
NVIDIA kernel module from obtaining ownership of the NVIDIA graphics
device(s), or no NVIDIA GPU installed in this system is supported by
this NVIDIA Linux graphics driver release.

    Please see the log entries 'Kernel module load error' and 'Kernel     
    messages' at the end of the file '/var/log/nvidia-installer.log' for  
    more information.

lspci does not show the cards

[root@dfm1 ~/Downloads]# lspci -vvv | grep -i -A 20 nvidia
[root@dfm1 ~/Downloads]#

[root@dfm1 ~/Downloads]# dmesg |grep NVRM
[67255.618984] NVRM: No NVIDIA graphics adapter found!
[67255.619029] NVRM: NVIDIA init module failed!
[411917.309274] NVRM: No NVIDIA graphics adapter found!
[411917.309322] NVRM: NVIDIA init module failed!

Any help would be greatly appreciated.

The installer log pretty much says what I have above.

The fix… Disable the on-board video in the BIOS.
