3Com NIC Diagnostics Program

Use the 3Com NIC Diagnostics program for Windows 95 and Windows NT to test the 3C905B-TX NIC and change conﬁguration. To change the NIC’s conﬁguration, see Chapter 5.

The 3Com NIC Diagnostics program is installed with the driver. Driver installation is described in Chapter 3. You must install the driver before you run the program.
