Mike, The clock ratio is probably the multiplier for the processor and probably needs to be set for the correct value. If I knew what motherboard (http://duxcw.com/digest/Fromshop/mb/det.htm) / computer make and model and CPU you had I could probably provide more specific advice.
Yes, you do have a network to the MODEM. See http://duxcw.com/faq/network/logdomain.htm for solving the login nuisance.
The display adapter determines the number of colors and resolution. Right-click the Windows Desktop, choose Properties, Settings, and see if you can change it there. If not, you may not have the correct driver installed for the adapter. Larry
