The prototype File

To install a driver at the time of installation, you must include the object and configuration files for the driver in the prototype file.

In this example, the executable module for the driver is named buffer; the add_drv command operates on this file. The kernel uses the configuration file, buffer.conf, to help configure the driver.

i pkginfo
i request
i postinstall
i preremove
f none $KERNDIR/buffer 444 root root
f none $KERNDIR/buffer.conf 444 root root

Looking at the prototype file for this example, notice the following:

• Since no special treatment is required for the package objects, you can put them into the standard none class. The CLASSES parameter is set to none in the pkginfo file.

• The path names for buffer and buffer.conf begin with the variable $KERNDIR. This variable is set in the request script and allows the administrator to decide where the driver files should be installed. The default directory is /kernel/drv.

• There is an entry for the postinstall script (the script that will perform the driver installation).
