Always backup your data prior to making any configuration changes. ITS is not responsible for loss of data.
This procedure requires some technical knowledge as it changes the network settings. If a computer person is available, please consult with him or her before proceeding.

ITS has standardized on the 3com Ethernet 10baseT network cards. If using another network card, use the appropriate drivers. ITS has also purchased a site license for the University community to use Trumpet Winsock. Should you decide to follow these instructions using our standard configuration, it is assumed that you are a UH faculty, staff, or student. Please click on the following links to download the necessary software for your installation needs, then save each file on a separate floppy diskette: 

  1. Trumpet Winsock
  2. 3com packet driver

Follow these steps to install the network driver in a PC running Windows 3.x:

Installation of Trumpet Winsock:

  1. Windows 3.1 should already be on your desktop before installing the Network Interface Card (NIC).
  2. Power off your computer; install the NIC and connect it to the network cable.
    (Check your manuals for installation of adapter cards.)
  3. Restart your computer.
  4. After Windows has restarted, insert the diskette that contains Trumpet Winsock in your floppy drive.
