CentOS 7 minimal install can't detect ethernet

If you're dealing with VMWare try following:
I added the following line to my .vmx file:
ethernet0.virtualDev = "e1000"

I recently installed CentOS 7 on my desktop computer and decided on the minimal install. It couldn't find a network device in the installation process, but I went ahead and installed it anyway. /etc/sysconfig/network-scripts/ifcfg-eth0 didn't exist to start. ifcfg-lo was the only one:
[chris@piecework4 /]$ ls /etc/sysconfig/network-scripts | grep ifcfg- ifcfg-lo
I made ifcfg-eth0 with the following values:
DEVICE="eth0" BOOTPROTO=dhcp NM_CONTROLLED="no" PERSISTENT_DHCLIENT=1 ONBOOT="yes" TYPE=Ethernet DEFROUTE=yes PEERDNS=yes PEERROUTES=yes IPV4_FAILURE_FATAL=yes IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_PEERDNS=yes IPV6_PEERROUTES=yes IPV6_FAILURE_FATAL=no NAME="eth0" HWADDR=00:13:D4:37:42:39
ifconfig -a only shows this:
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 0 (Local Loopback) RX packets 8 bytes 560 (560.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 8 bytes 560 (560.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
I do have an Ethernet controller...
[chris@piecework4 /]$ lspci | grep Ethernet 00:04.0 Ethernet controller: Silicon Integrated Systems [SiS] SiS900 PCI Fast Ethernet (rev 90)
Ethernet works fine on every live cd I try.
