The 3Com® 3C905B-TX network interface card (NIC)
provides a high-performance connection to an Ethernet or
Fast Ethernet network. This NIC operates at 100 Mbps or
10 Mbps automatically, depending on the speed of the
connected hub.

There are two types of 3C905B-TX NICs: the 3C905B-TX NIC
and the 3C905B-TX-NM NIC.
The 3Com Remote Wake-Up NIC (3C905B-TX), shown in
Figure 1-1, operates as a wake-up NIC only in PCs with the
Remote Wake-Up connector attached to the PC
motherboard. This NIC provides a network connection with
or without the Remote Wake-Up connector installed.
The 3C905B-TX-NM NIC does not have the Remote Wake-Up
connector or functionality.
