Does the problem appear to be resolved?
Ye s . No further steps are necessary.
No. Proceed to the next section, “Eliminating Resource Conflicts,” and to
“Getting Help” found later in this chapter.
Eliminating 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 devices may be installed at different times, 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 sys-
tem failure. If you suspect that resource conflicts might exist, check the
system and reassign the resources as necessary.
For additional information, see Chapter 5, “Using the Resource Configuration
Utility,” in the User’s Guide or “Interrupt Assignments” and “DMA Channel
Assignments” in Chapter 1 of this manual.
Running the Dell Diagnostics
The Dell Diagnostics contains tests that aid in troubleshooting all major com-
ponents of the computer system. To run the tests, you must first create a
diagnostics diskette using the Dell Server Assistant CD as described in
“Create Diskettes” in Chapter 2 of the User’s Guide.
To start the Dell Diagnostics, turn off the system, insert a diagnostics diskette
into drive A, and then turn on the system.
Starting the diagnostics causes the Dell logo screen to appear on the monitor
screen, followed by a message indicating that the diagnostics is loading.
Before the diagnostics loads, a program tests the portion of main memory
(RAM) required for loading the diagnostics. If a RAM error is detected, a mes-
sage appears on the screen telling you which DIMM has failed.
