Description of Fields

The General Options command allows you to select how the RF3880 adapter treats system and SCSI operation. The options you can select are general to the entire SCSI bus. Other options are available to you on a per unit basis with the Unit Options command and Extended Unit Options command.

The options of this command need only be set once during initialization; they will remain in effect until the next General Options command is issued or until the adapter is reset.

The Parameter Block for the General Options command looks like this:

Each field of the Parameter Block is explained below:

Address		Byte Memory Address
Offset	Offset + 0	Offset + 1	Offset + 2	Offset + 3
	Offset + 0	Offset + 1	Offset + 2	Offset + 3
00H		Command Identifier

04H	Select Flags	Bus Throttle	SCSI Bus ID	Adapter ID = FFH

08H		Reserved

0CH		Reserved

10H	Command = 07H		Reserved

14H		Reserved
18H		Reserved

Note

You can use the Board Information command (7 - 32) to find out what ID the jumpers are set to without physically examining the board.

Table 71: General Options Command Parameter Block

Command Identifier

The Command Identifier field is used to identify the Status Block associated with a Parameter Block. It must be a unique value.

Adapter ID

The General Options command is a Board-control command. This value must be FFH.

SCSI Bus ID

Each device that is connected to the SCSI bus must have an ID in order to communicate on the bus; the initial SCSI ID of the RF3880 adapter is set through jumpers. (See Chapter 3 for information on setting the jumpers.)

This field of the General Options command allows you to select a different ID than the one jumpered for the adapter, without changing the jumpers. This can be useful to avoid conflicts caused by duplicated ID’s at pow er-up.

Valid values are 0 - FH.
