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.
