System resources
Currently allocated system resources
All system resources (hardware addresses, memory utilization, interrupt assignment, DMA
channels) are assigned dynamically by the Windows operating system, depending on the
hardware equipment, drivers and connected external devices. You can view the current
allocation of system resources or possible conflicts in the Control Panel.
Procedure
To view the system resources, proceed as follows:
1.
Right-click the Windows Start menu and select "Device Manager".
2.
Click on the
View
menu and turn on " Resources by type" or "Resources by connection".
All the interrupts show under the Interrupt request (IRQ) catalog.
