* Multiple-function adapters containing storage typically respond as storage.

** The adapter IDs hex 7DB8 through 7DBF are reserved for the prototyping, developing, and testing of adapters and adapter designs and for adapters used in the testing of system designs.
Note: Do not use these IDs for purposes other than the local development of your adapters or systems.

Warning! Not all manufacturers and products adhered to these guidelines! Many exceptions exist and unfortunately even some adapter IDs are shared by two or more unique boards...
