SCSI Bus Interface Definitions
Host Adapter SCSI ID-(Default: 7) Sets the SCSI ID for the SCSI
controller. The Adaptec SCSI controller AIC-7899 is set at 7, which
gives the highest priority on the SCSI bus. We recommend that you do
not change this setting.
SCSI Parity Checking-(Default: Enabled) When set to Enabled, veri-
fies the accuracy of data transfer on the SCSI bus. Leave this setting
enabled unless any SCSI device does not support SCSI parity.
Host Adapter SCSI Termination-(Default: Automatic) Determines
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 ter-
mination as needed depending on the configuration 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 don’t 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
SCSI Device Configuration
SCSI Device Configuration options can be set individually for each con-
nected SCSI device.
Sync Transfer Rate-(Default: 160) Determines the maximum syn-
chronous data transfer rate that the SCSI card supports. Use the maxi-
mum value of 160 MBytes/sec.
Initiate Wide Negotiation-(Default: Yes) When set to Yes, 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: To configure settings for a SCSI device, you
must know it.s SCSI ID
