A. The easiest way to view resource usage by devices is to use the built in WINMSD.EXE utility supplied with Windows NT:

  1. Start the WINMSD.EXE utility (Start - Run - winmsd)
  2. Click on the resources tab
  3. You can then view any of the following:
    - IRQ
    - I/O Port
    - DMA
    - Memory
    - Devices
    By clicking the appropriate button
  4. When finished click OK to close WINMSD

You could also use the winmsdp.exe utility that is supplied with the resource kit. The command

winmsdp /i

will output the IRQ usage information to the file msdrpt.txt.
