Reading Time: < 1 minuteIf you have a new NIC card or a server of a new generation could be possible that the right driver is missing in the standard ESXi installation ISO. And without a working networking is not possible install the ESXi (the installation will stop because one requirement is at least a supported NIC).
Maybe the hardware vendor has a customized version of the ISO, but IMHO I don’t like this option (in some cases it could give some issues).
Another option is simple build your own customized version of the ESXi installation ISO and use it to install it with the right driver (custom drivers are usually avaible also on VMware site). To do this there are different options:
- Official way: use vSphere ESXi Image Builder CLI (as described in the relative section of the vSphere Installation and Setup Guide). A good guide is available on this post.
- Un-official way: use ESXi-Customizer (available as a free download). There is a good guide on how use this tool.
