We are using ESXI 5.5. I installed driver for this NIC: Intel® Ethernet Server Adapter I340-T4.
(we used vSphere PowerCLI to install these driver files: igb-3.2.10-504656.zip, igb-4.2.16.8-1242301.zip, igb-5.2.5-1682588.zip by the way: input command line Example: Add-EsxSoftwareDepot D:\igb-3.2.10-504656.zip)
But after restart ESXI, still cannot see this NIC.
Mainboard: Gigabyte GA-H67MA-USB3-B3.
