O seu computador possui duas NICs Via Rhine Fast Ethernet muito antigas .
Os drivers para essas NICs muito antigas foram removidos do RHEL / CentOS 7.
O driver ainda está presente no RHEL / CentOS 6, que será suportado por mais alguns anos. Então, você pode usar esse sistema operacional se realmente precisar desses NICs.
Provavelmente, a melhor coisa a fazer, no entanto, é se livrar do antigo computador.
