Chapter 7 Board-control Commands
Using the Reference Page 7 - 3
Using the
Reference The RF3880 adapter recognizes the type of command it is receiving by the
contents of the ID field of its parameter block. If the ID field contains a number
between 0 and 15 (indicating a SCSI address) the command is a Pass-through
command. If the ID field contains an FFH, the adapter recognizes it as a Board-
control command. This chapter explains only the Board-control commands.
The ID field will always be set to FFH for these commands. In this chapter it
is referred to as the Adapter ID field.
Each of the Board-control commands are completely described in the following
pages; each description follows the same format:
• First the Parameter Block format is illustrated for each command. The
fields that are valid appear in bold type.
• Next, each field used by the command is explained.
• Last, if there is a special type of Status Block returned by the command,
it is displayed and all of its fields explained.
