3.3.7.3 Initiate Wide Negotiation
This option allows communication between all devices (lower 8-bit or upper 8-bit) on the wide
(16-bit) SCSI bus. When set to Yes, each device can connect on the bus. When set to No
(disabled), communication can only occur on the lower eight bits of the 16-bit SCSI bus. The
default setting is Yes.
3.3.7.4 Enable Disconnection
This option determines whether the SCSI controller allows a SCSI device to disconnect from the
SCSI bus (sometimes called Disconnect/Reconnect). Disconnect/Reconnect allows the SCSI
controller to perform other operations on the SCSI bus while the SCSI device is temporarily
disconnected.
When set to Yes, the SCSI device may disconnect from the SCSI bus. The SCSI device, however,
may choose not to disconnect, even if permitted by the SCSI controller. When set to No, the SCSI
device is not allowed to disconnect from the SCSI bus. The default setting is Yes.
Keep this item set to Yes if two or more SCSI devices are connected to the SCSI controller. This
can optimize SCSI bus performance. If only one SCSI device is connected to the SCSI controller,
set this item to No to achieve better system performance.
3.3.7.5 Send Start Unit Command
This option determines whether the Start Unit Command (SCSI command 1B) is sent to the SCSI
