setfdprm is a utility that can be used to load disk parameters into the auto-detecting floppy devices, to clear old parameter sets and to disable or enable diagnostic messages.

Without any options, setfdprm loads the device (usually /dev/fd0 or /dev/fd1) with a new parameter set with the name entry found in /etc/fdprm (usually named 360/360, etc.). These parameters stay in effect until the media is changed.

?p device name

Permanently loads a new parameter set for the specified auto-configuring floppy device for the configuration with name in /etc/fdprm. Alternatively, the parameters can be given directly from the command line.

?c device

Clears the parameter set of the specified auto-configuring floppy device.

-y device

Enables format detection messages for the specified auto-configuring floppy device.

-n device

Disables format detection messages for the specified auto-configuring floppy device.
