3Installing NIC Drivers and

Diagnostics For Windows

This chapter explains the following tasks on a computer running Windows 2000,
Windows NT, Windows Millennium Edition (Windows Me), Windows 98, or Windows 95:
Install the network driver and NIC software using EtherCD
Update the network driver or NIC diagnostics program
Install multiple NICs
To obtain the latest version of a driver, go to:
http://www.3com.com/
Search for “3C990B” and “drivers.” The network driver can be used in both Microsoft
and NetWare network environments.

Software Installation Requirements

If your site network installation procedures require you to verify that installed hardware is
functional before you install software, you can verify that the installed NIC is functional or
change its configuration settings by running the DOS diagnostics. Use the 3C99XCFG.EXE
program located on the EtherCD. For more information, see “Using the 3Com DOS
Configuration Program” on page 77.
If you are installing the software during the installation of the network operating system,
see “Installing a 3Com NIC While Installing the NOS” on page 107.
For a list of minimum installation prerequisites, see “Installation Requirements” on page 14.

Getting Help

To display the Help system during the software installation, click Help on any 3Com window.

Installing the Network Driver Using the EtherCD

To install the network driver using the EtherCD, follow the steps in the section that is
specific to your Windows operating system.
Before Installing the Network Driver
Before installing the network driver, make sure that:
The NIC is installed in the PC and connected to the network. For instructions, see
“Installing and Connecting the NIC” on page 18.
All software installation requirements are met. See “Installation Requirements” on
page 14.
NOTE: For instructions on using the installation diskettes (which can be created
from the EtherCD) to install the network driver, see “Installing From Diskette” on

in the HELP directory on the EtherCD.
