As one adds more hard drives to a system, knowledge of the fstab file becomes more and more necessary. The following web site has already done a good job explaining fstab so there is no need to reinvent the wheel.

Create an interface manually

Just copy the following lines into a file called ifcfg-eth1 and drop it in the “/etc/sysconfig/network-scripts” folder.

then do a “service network restart”

DEVICE=eth1
ONBOOT=yes
BOOTPROTO=static
BROADCAST=10.1.255.255      <-- replace with own
HWADDR=00:00:00:00:00:00   <-- replace with own MAC Address with your MAC Address
IPADDR=10.1.0.123                       <-- replace with own
NETWORK=10.1.0.1                   <-- replace with own gateway
NETMASK=255.255.0.0              <-- replace with own network mask
TYPE=Ethernet

DEVICE=eth1
ONBOOT=yes
BOOTPROTO=static
BROADCAST=10.1.255.255     
HWADDR=00:00:00:00:00:00  
IPADDR=10.1.0.123                      
GATEWAY=10.1.0.1                  
NETMASK=255.255.0.0             
TYPE=Ethernet

The naming convention is crucial please pay attention to that.

The equivalent of msinfo32 in windows could easily be : dmidecode in linux redhat flavor.

So many linux flavors so little time, YCSoftware decided to stick to anything REDHAT.  I assume that you are using one of them.

2. You may also try lspci for pci devices

3 or lsusb for usbdevices

4.  dmesg
