The d option configures one device interactively. This is how you load drivers that aren't specified in the system configuration, and is generally used to test a device driver. For example, specifying the -d option as in this command:
/usr/etc/driverLoader d=Adaptec1542B
initiates an interactive dialog (user input in bold):
Answer queries with 'y' for 'yes', anything else is 'no'. Execute Pre-Load file (pre-load filename)? y Load driver Adaptec1542B? y Configure driver Adaptec1542B unit 0? y Execute Post-Load file (post-load filename)? y
The queries about Pre-Load and Post-Load files only appear if the driver supports such files. The filenames for the Pre-Load and Post-Load files are specific to a given driver.
You provide the instance argument to specify an Instancen.table file. For example, if you specify instance as 1, the driver will be probed using the information in its Instance1.table file.
/usr/etc/driverLoader d=fooDriver 1
