How to Use the Diagnostic Utility

The diagnostic utility is a DOS program. It can be run directly from the ATMDisk diskette or copied, with its help file, to the system hard drive and run from a directory of your choice.

The diagnostic utility must be run from DOS with no network drivers loaded. Table 6-1 describes the suggested method of accessing DOS from your network operating system (NOS).

The diagnostic utility cannot be run from an MS-DOS window.

Table 6-1 Accessing MS-DOS

NOS	Method of Accessing DOS
Novell NetWare	Down the server and exit to DOS.
Windows NT	Reboot the system with an MS-DOS system diskette
	(MS-DOS version 6.20 or later).

Starting the Diagnostic Utility

This guide documents the internal and external test procedures separately.

Make sure that the 3C975 ATMLink NIC is firmly seated in a functional PCI slot before running the diagnostic utility. (See Chapter 2 for hardware installation details.)

To run the diagnostic utility directly from the ATMDisk diskette, perform the following procedure:

1Shut down all applications and processes running on the Windows NT or NetWare system, and exit to DOS as described in Table 6-1.

2Insert the appropriate ATMDisk diskette in the floppy drive.

3Change to the root directory of the floppy drive and type:
