If it is not change it to start on Boot and then restart the computer. 2 Start NT Diagnostics (Start, Programs, Administrative Tools). 3 Under the Version tab note the Service Pack level. The NT 4.0 version is displayed as follows: MICROSOFT (R) WINDOWS NT (TM) WORKSTATION VERSION 4.0 (BUILD 1381: SERVICE PACK X) If no service packs have been applied on Version 4.0, (Build 1381:) is displayed. X is the service pack level, number 1 through 4. Service Packs integrate software upgrades to your current system and are available from Microsoft. 4 Select the Resources tab. By default the IRQ levels in use are displayed. Verify that the IRQ assigned to the Xircom card is not in use by any other device. This list is not inclusive and may not be completely indicative of resources in use. 5 Click the I/O Port button. Verify that the I/O Port Address assigned to the Xircom card is not shared by any other device. I/O Port 0x280 is usually available. This is displayed as: 0280 - 028E CEM56 BUS 0 TYPE ISA For an I/O Port Address to be usable the entire I/O range must be available.
