configuration: MAC address and default gateway.
WINIPCFG (for Windows 95/98)
Inside the windows 95/98 Start button, select Run and type winipcfg. In the
example below this computer has an IP address of 192.168.0.100 and the
default gateway is 192.168.0.1. The default gateway should be the network
device IP address. The MAC address in windows 95/98 is called the Adapter
Address.
NOTE: You can also type winipcfg in the DOS command prompt.
