PowerEdge R720XD OS installation

I am unable to install ESXi because the OS installation cannot detect any network cards on the server despite it having 4.

These are the error messages i get on post:

Plug and Play Configuration Error:

Device Location table Error

Bus#01/Dev#00/Func#0: Unknown PCI Device

Plug and Play Configuration Error:

Option ROM Device Location table Error

Bus#01/Dev#00/Func#0: Unknown PCI Device

Plug and Play Configuration Error:

IRQ Allocation

Bus#01/Dev#00/Func#0: Unknown PCI Device

Does this look like a faulty motherboard or Network card device?

Thanks,

Dave
