Installing NIC Drivers and
Diagnostics For Windows
This chapter explains the following tasks on a computer running Windows XP Professional
Edition, 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:
1 Go to:
http://www.3com.com/
2 Click Downloads.
3 Search for “3CR990” 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 50.
If you are installing the software during the installation of the network operating system,
see Appendix D, “Installing a 3Com NIC While Installing the NOS.”
For a list of minimum installation prerequisites, see “Installation Requirements” on page 10.
Getting Help
To display the Help system during the software installation, click Help on any 3Com window.
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
page 11. For additional information, refer to the text file for your operating system
in the HELP directory on the EtherCD.
