Eliminating Resource Conflicts - Dell Precision 410 Service Manual

2-6 Dell Precision 410 Systems Service Manual
If you need to reseat an expansion card, use a
remove the screw that secures the card-mounting bracket. Grasp the card
by its top corners, and carefully pull it out of its connector. Reinsert the
card in its connector, and carefully push it in until it is fully seated. Then
reinstall the card-mounting bracket's retaining screw (see "Expansion
Cards" in Chapter 4 or 5 for more information).
For information about these jumpers, see "System Board Jumpers" in
Chapter 1.
Does the problem appear to be resolved?
Yes. No further steps are necessary.
No. Proceed to "Eliminating Resource Conflicts," "Running the Dell Diag-
nostics," and "Getting Help" found later in this chapter.
Devices within or connected to the computer may require dedicated memory
spaces, interrupt levels, or DMA channels, all of which must be allocated dur-
ing 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 failure
of the system to operate at all. If you suspect that resource conflicts might
exist, check the system using the Windows 95 Device Manager or the ISA
Configuration Utility (ICU), and reassign the resources as necessary. See
"Advanced Expansion Subsystem" in Chapter 1 for information on the Device
Manager and the ICU. See "Interrupt Request Assignments" in
Chapter 1 to help identify possible conflicts. Also review the documentation
provided with any installed expansion cards and other devices for additional
interrupt information for the specific devices.
