3. Configuration
Advanced Options
Boot Device Configuration
Boot SCSI Controller(Default: A First) Specifies which of the two SCSI
channels the boot device is connected to (if the computer boots from a SCSI
device). If you change this setting, the change automatically applies to both
SCSI channels.
Boot SCSI ID(Default: 0) Specifies the SCSI ID of your boot device. We
recommend that you do not change the default setting. If you change this setting,
the change automatically applies to both SCSI channels.
Boot LUN Number(Default: 0) Specifies which LUN (Logical Unit Number)
to boot from on your boot device. This setting is not valid unless Multiple LUN
Support is enabled (see Advanced Configuration on the next page). If you change
this setting, the change automatically applies to both SCSI channels.
SCSI Device Configuration
SCSI Device Configuration options can be set individually for each connected SCSI
device.
NOTE: To configure settings for a SCSI device, you must know its
SCSI ID (see 3.2.4 Using SCSI Disk Utilities).
Sync Transfer Rate(Default: 160) Determines the maximum synchronous data
transfer rate that the SCSI card supports. We recommend that you leave the
maximum (default) value of 160 MBytes/sec.
Initiate Wide Negotiation(Default: Yes ) When set toYes, the SCSI card attempts
16-bit data transfer (wide negotiation). When set to No, the SCSI card uses 8-bit
data transfer unless the SCSI device requests wide negotiation.
NOTE: Set Initiate Wide Negotiation to No if you are using an 8-bit
SCSI device that hangs or shows other performance problems with
16-bit data transfer rate enabled.
Enable Disconnection(Default: Yes) When set toYes, allows the SCSI device
to disconnect from the SCSI bus. Leave the setting on Yes if two or more SCSI
devices are connected to the SCSI card. If only one SCSI device is connected,
changing the setting to No results in slightly better performance.
Send Start Unit Command(Default: Yes) When set to Yes, sends the Start Unit
Command to the SCSI device at bootup.
