[CentOS] Centos7 Net install on HP A1710N fails

Folks:

This conversation was trying to get Centos 7 installed on a machine 
with a NIC that got de-supported in EL7.

Following the advice to do as follows:
  - Install (via CD) the "minimal" ISO
  - add the RPM of kmod-forcedeth-0.64-1.el7.elrepo.x86_64.rpm  from 
a USB stick, as obtained from ELPRO (install went without serious complaint)
I'm at a loss of what to do next, namely
  - How do I tell Centos that there's a NIC, and how do I configure it?

PS:  There is no GUI, and the command line display is very tiny.

Guidance would be appreciated.
