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.

Note:

To configure settings for a SCSI device, you

 

must know it.s SCSI ID

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.
