Adding and Removing ISA Cards

run its conflict detection algorithms on the resources requested by the cards.
This alerts you to any possible problems with that particular card in the current
configuration.
To add an ISA card:
1. Click on Add ISA Card in the RCA window.
2. Specify the directory for the .CFG file.
3. Select the file and click on Ok.
To remove an ISA card:
1. Select a valid ISA card in the Devices section of the RCA window.
2. Click on Remove ISA Card.
