liminating Resource Conflicts
Devices within or connected to 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 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 Configura-
tion Utility (ICU), and reassign the resources as necessary. See “Advanced
