What Addresses Are in Use on My NT Machine?
Problem: "I am setting up the AT card on my NT computer and the address that I selected with the DIP switches is not working. How do I know what addresses are already in use by other hardware on my computer?"
On your Start menu go to the following location:
Start
Programs
Administrative Tools
WinNT Diagnostics
Resources
I/O port
Here you can see all the devices that are using the bus and the address they occupy.
