112 PCA-6180 User’s Manual
this setting enabled unless any SCSI device connected to the
Adaptec SCSI Card 29160 does not support SCSI parity.
• Host Adapter SCSI Termination—(Default: Automatic) Deter-
mines the termination setting for the SCSI card. The default setting
for both the LVD/SE (low voltage differential/single ended)
connectors and SE connectors is Automatic, which allows the SCSI
card to adjust the termination as needed depending on the configu-
ration of the connected SCSI devices. We recommend that you do
not change these settings.
Boot Device Options
• Boot SCSI ID—(Default: 0) Specifies the SCSI ID of your boot
device. We recommend that you do not change the default setting.
• 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 Options on page 115).
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 Using SCSI Disk Utilities on
page 23).
• Sync Transfer Rate—(Default: 160) Determines the maximum
synchronous data transfer rate that the SCSI card supports. Use the
maximum value of 160 MBytes/sec.
• Initiate Wide Negotiation—(Default: Yes) When set to Ye s , 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.
