Table 8.2.1.4 : ANSI-approved version
An Asynchronous event notification capability (AENC) bit of 1 indicates that
the autoloader supports the Synchronous event notification capability. Because
this autoloader does not support the Synchronous event notification capability,
this field is 0.
When Terminate I/O process (TrmIOP) is 1, the autoloader supports the
TERMINATE I/O PROCESS message. Because this autoloader does not
support TrmIOP, this field is 0.
Response data format is set to 02h, which indicates that the autoloader supports
the International Standard version of SCSI-2.
The Additional length field indicates the length of the parameter region in bytes.
Because this autoloader has 31 bytes of parameters, this field is set to 1fh.
A RelAdr bit of 1 indicates that the autoloader supports relative addressing.
Because this autoloader does not support relative addressing, this field is 0.
A Wide bus 32 (Wbus32) bit of 1 indicates that the autoloader supports 32-bit
wide data transfers. Because this autoloader does not support 32-bit wide data
transfers, this field is 0.
A Wide bus 16 (Wbus16) bit of 1 indicates that autoloader supports 16-bit wide
data transfers. A Wbus16 bit of 0 indicates that the autoloader does not support
16-bit wide data transfers. Because this autoloader supports 16-bit wide data
transfers, this field is 1.
A Synchronous transfer (Sync) bit of 1 indicates that the autoloader supports
synchronous data transfers. A (Sync) bit of 0 indicates that the autoloader does
not support synchronous data transfers. Because this autoloader supports
synchronous data transfers, this field is 1.
A Linked command (Linked) bit is 1, this indicates that the autoloader supports
linked commands. Because this autoloader does not support linked commands,
this field is 0.
A Command queuing (CmdQue) bit of 1 indicates that the autoloader supports
tag command queuing. Because this autoloader does not support tag command
queuing, this field is 0.
A Soft reset (SftRe) bit of 1 indicates that the autoloader supports soft resets.
Because this autoloader only supports hard resets, this field is 0.
