The OptiPlex GX1 systems use either diskette-based or server-based diagnos-
tics. The OptiPlex NX1 systems use either server-based, hard-disk–based or
optionally diskette-based diagnostics using an external diskette-drive kit con-
nected to the computer as shown in Figure 2-1 and described in the following
procedure.
The diskette-based diagnostics contains the same tests as the
hard-disk–based diagnostics. These tests aid in troubleshooting all major
components of the system.
