Adding Device Methods
Device methods must be added when adding system support for a new device.
Primary methods needed to support a device are:
When adding a device that closely resembles devices already supported, you might be able to use one of the methods of the already supported device. For example, if you are adding a new type of SCSI disk whose interfaces are identical to supported SCSI disks, the existing methods for SCSI disks may work. If so, all you need to do is populate the Predefined database with information describing the new SCSI disk, which will be similar to information describing a supported SCSI disk.
