is there a way to determine what ports are available? like if you wanted to read a floppy by port number?

For devices that are plug-and-play this is apparently simple but I don't know the details.

As for older devices, you will have to look up programming guides for those devices

the basic devices (such as the FDD) are always located at a specific port (cannot remember offhand which one the FDD is), the RBIL has a list of ports, and what is commonly used for, also most MB manuals contain a list of standard port assignments (all the older ones did, but some of the newer ones don't)

## ---- ----- RBIL

thanks for the information. now to read it all for the basics
