System resources

A.5.1

Currently allocated system resources

All system resources (hardware addresses, memory configuration, allocation of interrupts,
DMA channels) are assigned dynamically by the Windows® operating system, depending on
the hardware configuration, drivers and connected external devices. You can view the
current configuration of system resources or possible conflicts with Windows® as follows:
1. Press the "Windows key" and "R" simultaneously.
The "Run" dialog box opens.
2. Enter "msinfo32" in the "Open" field.
3. Confirm your entry with "OK".
