liminating Resource Conflicts
Devices within the computer may require dedicated memory spaces, interrupt
levels, or DMA channels, all of which must be allocated during installation of
the devices. Because a device may be installed at a different time, it is possible
that the same resource is assigned to two or more devices.
Resource conflicts can result in disorderly or erratic system operation or failure
of the system to operate at all. If you suspect that resource conflicts might exist,
check the system and reassign the resources as necessary.

unning the System Diagnostics
The system diagnostics (included on the Dell Server Assistant CD) contains
tests that aid in troubleshooting all major components of the computer system.
To start the diagnostics, insert the CD into the CD-ROM drive, and then press
the reset button on the computer.
Restarting the computer causes a program to test the portion of main memory
(RAM) required for loading the diagnostics. If a main memory error is detected,
a message telling you which DIMM has failed appears on the screen. Other-
wise, the Dell Server Assistant logo screen appears on the monitor, followed by
a screen containing icons of the options available.
If no errors are found in main memory and the Dell Server Assistant loads,
select the Run System Utilities icon. Then select the Run System Diagnostics
icon and press <Enter>. The Diagnostics Menu appears, allowing you to choose
among the following options or exit to MS-DOS:
•
Run All Tests — Runs all tests for a thorough check of the system
•
Run Quick Tests — Runs selected tests from all test groups to quickly locate
a failure or to indicate where further testing is needed to isolate a failure
•
Run Specific Tests — Tests a particular area or subsystem
