Windows 2000 and WIndows XP offloading features.

Hot Swapping

If your computer supports hot swapping, you can add a new 3Com LAN PC Card
or remove and replace a 3Com LAN PC Card without turning off power to the
computer. Hot swapping lets you expand connections without taking the
computer out of service. It makes troubleshooting faster and easier because you
do not need to wait for the computer to restart.

Offline Diagnostics

The 3Com Firewall PC Card includes offline diagnostics programs for configuring,
testing, and troubleshooting PC Cards. The configuration program within the DOS
diagnostics program is used for a notebook running DOS or NetWare. The LAN
diagnostics program (3Com NIC Doctor) is a windows-based program used for a
PC running Windows XP, Windows 2000, Windows NT 4.0, or Windows 98. This
program may also be used to flash upgrade the PC card.
